Boxing Game

Would it be possible to create a simple 3D boxing game in blender?

-It would be 2 player
-Your character would move left right forward backward, there would only be head shots, one type of punch, and left and right punches assinged to two different keys.
-The character that gets hit (50) times first rag dolls on the ground
Basically rock em’ sock em’ robots with moving targets.

I think I would have trouble with the opponents always facing each other and hit registration.

Any thoughts?
