Hey Yoshiboshi!
I have a request fitting your guidlines, off of the existing master chief vertex.
Pretty much his face would be smoothed out, so the visor wouldn't protrude.
I'm going to use it for some neat Star Wars textures. It should be universal enough to be used for other simple-helmeted characters, if other kc-mm members decide to use it.
Anyways, here's the thread for more info.
http://forums.kc-mm.com/index.php?topic=9613.0if you decide to work on it, I'll make sure to leave a note + link. I feel sorry for others who make hacks exactly the same as someone else's, at the same time. Especially if it was only because of a lack of communication.
Good luck, and thanks for reading!
