It seems like the easiest way to do that would be to leave the sun stuff 
in /usr/bin (for all the reasons you wrote above, and more) and stick 
/usr/gnu/bin first in the default path of all users (probably except root.)

Isn't that the best of both worlds?

The /usr/has/bin thing is really orthogonal, since it's not a sun v.s 
gnu thing. It's an old Sun/SVR4 vs. new Sun/SVR4 thing.
