It's just too bad that we'll lose the performance gained from the fact that GCC's CPP is linked into the C compiler binary and thus doesn't have to transfer it's result over a pipe or anything like that.
I really think this whole idea isn't a very smart one. I would rather have whoever would be working on a sparse backend instead be working on kernel improvements.
I also think people underestimate how much work this would be.
