Yet group size matters. Anyone can start an organization, be it Mormons for Marxism, the Mormon Badminton League, or the Mormon Transhumanist Association. If such an organization is unable to attract more than a handful of Mormon members, it probably is not representative of Mormons or Mormonism.
How representative of what fuels their content comes directly from Mormon beliefs & past Mormon leadership comments?
Your question is unclear. Would you care to rephrase it?
And, how much traction do their comments receive in broader Mormon literary circles?
I am not sure what circles you have in mind.
To repeat what I wrote previously, the "Mormon Transhumanist Affirmation" strikes me as more Transhumanist than Mormon.
If a religious Organization® can only attract a membership of around 12-13 million in a world of 6,000,000,000 beings - then it probably does not represent Christians or Christianity.

OK. These "transhumanists" suggest, according to the article, that they are (at least in part) fueled by basic long-held lds beliefs:
Article: By way of background information, The Mormon Transhuman Association embraces an idea that Joseph Smith and other early LDS leaders taught, which is that God is an exhalted man. God Himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! - Joseph Smith
Lds connection: Lds have taught that somehow their man-become-god became exalted. (According to the article, The Mormon Transhuman Association embraces [that]...idea)
Article: According to this early belief, our God was able to advance until he attained his current status: God and creator of worlds. This teaching promises that the same is true for all of us, and that we can go on to do the same, perpetuating the cycle of building worlds and raising gods...Further, as we advance ourselves, we too may go on to build worlds. This logical argument, then, meshes nicely with the LDS belief.
Lds connection: Lds have taught that the universe incorporates many habitable planets or stars (Kolob, etc.). Obviously, inhabitants of these stars are to "earthlings" -- something of an "alien" variety...and Lds teachings focus on celestial-rank people populating these planets/stars in the next life (Transhumanists embrace this idea of an advanced mortal civilization living on other built-up planets)
Article: ...it is reasonable to conclude that we are the product of an advanced civilization. Further, as we advance ourselves, we too may go on to build worlds. This logical argument, then, meshes nicely with the LDS belief.
Lds connection: Lds teach "eternal progression" of mortals, which seems to be the foundational belief of transhumanists...that men who advanced unto godhood-like status turned around & generationally are now assisting in the progression of their spiritual offspring as they, too, move on to build other worlds.
Bottom line: If you take the literal definition of the word, "transhumanist," all it means is a human who either changes or moves across (as in moves across dimensions & time & space). Lds have long taught that "father" Elohim was...
(a) part of a broader scheme of gods -- a council of gods;
(b) was a mere human under one or more of these gods and "advanced" -- changed, progressed, moved across dimensions...etc.
(c) and Lds prophets like Spencer W. Kimball and others have stressed how people on earth today can likewise "pull themselves up by the bootstraps" to become "gods" as well.
It seems to me that some of these "transhumanist" beliefs align themselves quite well with Lds thought. (Partially agree? Disagree? Why?)
