"Should the Holy Hexagram be traced "averse"?"
That's not the way it was written. - I'm not all that sure that there is any pronounced relationship between Liber 36 and the text in the later chapter you quote.
But, in any case, notice that the first stroke of drawing the Hexagram is a "plunging" downward. (And the reversal of the colors in that particular design doesn't reverse the Hexagram, it just changes the colors - colors that wouldn't be used in The Star Sapphire in any case any more than the reversed ones are used in the standard Lesser Ritual of the Hexagram.)"
Actually, there are within the GD differing opinions on that one and both LRH and LBRP has been given with different instructions throughout time.
Doing the Hexagrams red / blue would not be considered "wrong" by any GD people i´ve experienced, though gold by nature corresponds to Tiphareth and thus would be apropriate.
Another alternative would be yellow apex up, purple apex down (still corresponding to Tiphareth though including coplementary colour, purple being complementary of yellow)
"If the Hexagram is traced normally, only changing its colours, the holier part of it would not be descending but behaving rather normally save for an Elemental "hue" of an oposite kind.
"Except, again, in actually doing a hexagram ritual these colors aren't used. The custom has always been to draw the hexagrams entirely of golden yellow light (except in the planet-specific Greater Ritual)."
While i feel, right or wrong, that there must have been a reson for Crowley writing "Holy Hexagram" and not only Hexagram.
Simply tracing a yellow Hexagram the normal way would be undistinguishable from tracing a normal Hexagram.
In theory i can even see the Ritual used in Planetairy specific operations though it would loose so much of it´s HGA symbolism that it should propably not be called the Star Saphire if used that way.
""In the magical hexagram this is revered; the descending red triangle is that of Horus, a sign specially revealed by him personally, at the Equinox of the Gods. (It is the flame desending upon the altar, and licking up the burnt offering.) The blue triangle represents the aspiration, since blue is the colour of devotion, and the triangle, kinetically considered, is the symbol of directed force.""
Yes.
"Then again, the Hexagram and HGA is centered at Tiphareth first and foremost, not the Supernals. I do however feel a bit inclined to believe that the power of the Ritual is supposed to pass down through Daath."
That's generally how Supernal consciousness penetrates into Ruach, yes 
"Another thing, if a Banishing is performed before the Star Saphire, using only Earth Hexagrams, the Hexagrams superimposed on eachother would yield 12 at each point, thus also invoking the Zodiac."
No, still six points. - They perfectly overlap. Butk, in any case, FWIW, I've never felt the need to do a banishing hexagram before the Star Sapphire. I've always prepared the temple by other means - but, in the same way that there is not an invoking Star Ruby (it is only for banishing), so is there not a banishing Star Sapphire (it is purely for invoking)."
My abeve reflection was due to the theory that the averse Pentagrams in the Reguli superimposed on the normal ones of the Star Ruby produces the Hexagram (if the Elementary four points are joined) wich is later declared in the Ritual itself by the cry ABRAHADABRA before the Pentagram section, the Unicursal Hexagram and Mater Triumphans sign after it, both "giving birth" to the Aeon and combining 5 with 6 (according to the theory).
The circambulations adding up to 11, the knock 3-5-3 also indicate this.
It feels a bit more plausible than the "Magician standing upside down" theory (though i have the utmost respect for Arch Bishop DuQuette).
Not that one theory negates the other in this case, both might be the "true".
This article takes up the theory (though i dont subscribe to the authors ideas on up side down VS averse).
www.rosslyn.org/articles/unicursalhexagram.htm
Turning a Hexagram clockwise (or anti clockwise) and superimosing it on a normal one would produce 12 at each point (3+9 and so on).
The number of points would not be altered, just the numerations if added together (lets not produce Star Saphire Dodekagrams here 
)
Also, "God" descending does in my eyes look more like the supernals than Yesod, while "the aspiration" does sound like Yesod.
"Another question, if the Star Ruby is only for Banishing and Star Saphire only Invoking, in what sence can they be said to "correspond" (exept for mathematically)?"
"Oh, they're a nice pair of hand-carved ummatched bookends made by the same artisan at the same time."
The way i see it, all Banishings being Invokations by nature, all Rituals can be utilized for both Invokative and Banishing purposes. In theory by replacing the first sign and utterance of the Star Ruby it could be turned Invokative. The Reguli is said to be "polyform" and i have used the Star Saphire as a Banishing for years, the result being that the qualities usually Invoked are now turned towards expelling what is unwanted for the work.
The same way i use the Reguli for Banishing (in conjunction with Star Ruby) in wich case the enrgies of the Aeon are turned to expelling unwanted forces.
The original qualites of the Ritual are still fully recognizable (energy wise).
I should however make clear that normally i use Reguli for Invokation and Star Ruby for Banishing.
""The Star Sapphire corresponds with the Star-Ruby of Chapter 25; 36 being the square of 6, as 25 is of 5. This chapter gives the real and perfect Ritual of the Hexagram.""
He was only speaking mathematically."
Perhaps we should be glad that we all have our theories and thoughts on the Rituals and apply them to our specific works and needs.
It shows that we are thinking after all.
Not denying folly or mistakes, the greatest folly would still be heard mentality.
You do bring up some really interesting points in your text and it is very inspirational to read.
