Would it be possible to make a mod that removes shadows from bodies, and perhaps even lowers the details a bit?

When I play a battle, look at a bunch of bodies and see my fps significantly drop, I pull this face:

I find that, while its lovely to see a battlefield strewn with highly detailed, realistic bodies, it's also a large performance hog, maybe even more so than when they were alive!

I don't really notice the shadows much on the bodies anyway, and detail is not as important to me when they're...well, dead.

This would be useful in large battles, as performance would increase, I believe, dramatically as the battle progresses.

So could someone perhaps make, or point me towards a mod that does something along the lines of this?
