Sure, if you have more experience with this and can help get this moving quicker, go for it - attached in the .zip are two .blend files that are the most recent before I "ruined" things trying to add a vest. One is just a half, which can be mirrored to make a complete model.
I've gotta warn you though, both of these still have a few issues, with a slightly mucked up neck, a belt that's too thin, and... uh, well, you'll see when you open the files and start working on them...
BTW, if it turns out you can get a working model completed quicker and better than I do, based upon these, I'll let you go ahead and pick a license that will fit with the game - I'm not going to bother with protecting these models in their current form with any restrictions, it just isn't worth it. (If any of the devs want to be meticulous with the licensing thing, I guess in the credits you could say "started by Destructavator" for anything based upon these models.)
