Luckily there are some GPU programmers here! I coded up my proposal and see less than a 5% performance impact (I measured 2-3% over 4 hours of work but with some margin of error)

I asked about distribution somewhere and was told that mfaktc is ~30% of GPU factoring so starting there would be a good idea.
