The best thing anybody can do to help would probably be to either learn to make unit models, and try to make as perfect a replica you can of the old units from RTW:EB engine to the M2TW engine. Most of the really hard work (research and such) is done for you this time around so you don't have to make new units, I'd leave that up to the EB team, that and making the armor variants. Of course if you can't or don't have the time to do this, you could always introduce a friend of yours who does know how to do 3d modeling to EB and get them to help out. Hell, you could do it yourself AND get a friend to do it if you really wanted to speed things up.
