Well we do have to "deal with SHA-2" as a change to a different hashing algorithm would be a hard fork and that isn't going to happen.
But it would kill two birds with one stone.
1) The ASIC madness would stop
2) The NSA algorithm would be gone.
By the way: What might have been the reason that Mr. Nakamoto decided to use an NSA algorithm (SHA-256) for Bitcoin?
