I think this would be good, even using the default bodies;
Using a courch gani, a prone gani, grenade throwing, And if you make good use of the particle system, and have a nice looking tileset, then this project would be extremely easy to maintain.

Seeing as we have ALOT of history on this subject to base map designs off, weaponry referances. And a nice 360 targetting system, similer way to how a bow on graal works, if courch and behind a certain ammount of tiles your covered, and if proned, 1 tile and so on.

That would probably work well.
