It won't, because the Avengers were barely anything in the Marvel world of the 90s. It was mostly X-Men, Cosmic stories, and probably Spider Man as the top content in those days.
Starlin stuff was almost purely cosmic: Thanos was his baby, and anything that ever mattered with regard to Starlin's Infinity stories always involved Warlock, Surfer, Galactus and other cosmic beings as the relevant entities. The earthbound heroes (except for Dr Strange, I think), were pretty much useless fodder in Starlin's world. Apparently, Marvel didn't really like Starlin's stuff, or he just annoyed them. whatever.
This is after I was reading comics, but I think there was some Thanos vs Avengers, massive storyline not too long ago--there is this expensive trade paperback that collects some 24+? comics that are involved in this story--that is Avengers vs Thanos. Apprently it's incredibly dumb (if you prefer Starlin's bizarre work, as I always did).
It's pretty clear that the Marvel Studios franchise is Avengers--bound, which from what I have read, as been the Marvel comics world focus for a while now. Everything has been leading to some massive Avengers vs Thanos storyline.
Were it Starlin's Infinity world, You would have 2 and a half acts of this creepy Warlock dude floating around between dimensions and consciousness, debating with ghosts of Thanos and fighting mental projections of Thanos. Warlock would then eventually recruit all of earth's heroes to help him; he would have them all slaughtered in a manner of seconds only to have Thanos distracted for those2 seconds, so Surfer could speed him across solar systems in that 2 second's time to help him snatch the glove, thus gaining omnipotence.
I don't think Marvel wants that in a film....but I would find it hilarious.
