Do you have a new model?
I have a new one that's almost finished, for both male and female, although just one armor type (plus a whole lot of camo textures) which is already in this forum, although it is in Blender format. Currently it is a high-detail version mostly for cinematic cut-scenes.
Sometime very soon (within a few days) I hope to have it finished and also have a low-poly version ready (for use in-game). When I finally roll it out as "finished" I'll also export it to other formats for modeling in other editors.
Vedrit (a skilled animator here) also built a skeleton for animating it already. You're welcome to download that one and base something off of it anytime.
Whatever the new models are based off of, they probably should be based off the same basic base model so they are consistent and match.
Edit: I will say though, that what I've seen you do so far with the old models looks impressive.
