Actually you can do it rather easily (MAX to MED) by exporting it as a .ASE file and then rigging / animating it in MED.

here's an example of a low-poly model I made last year...

he's roughly 2000 polys and has a painted on face and a 0 (zero) setting using meshsmooth (it takes away the hard edge without adding polys).

ALSO

you got WAAAY! to many polys in your hands and head; you don't need a million polys to make a finger REMEMBER less is more!
