I had a similar idea also involving evolution and lisp evaluation, to make something similar to Darwin bots.(http://www.darwinbots.com/WikiManual/index.php?title=Main_Page) I was a bit half-assed about it, though. And reading that code now.. it could be better, i wrote it quite a while ago. For one, i didn't conceptually separate genetics and their Darwinbot-like nature. (And i made way too many variables in the bots too early on.) Anyway, perhaps instead of evalling the genetic code, you can compile functions from them, it may be faster, depending on how many times the same genetic code is run between changing. Declare has a term for compilation speed too.. Sounds like a nice project!

I've got a lot of Lisp code sitting around from my Evolutionary Computation course, and am about to begin writing my own EC package in CL. this is great!
