It's an interesting idea that I hadn't thought of.  There would have to 
be an atomic file system operation to "commit" a compiled module - 
getting that right could be a bit tricky (compilation isn't 
deterministic, so the commit has to be atomic).

Then you would probably want to randomise the build order of each --make 
run to maximise the chance that each GHC does something different.

Fun project for someone?
