i'm pretty sure your plan will work fine. the things you'll need to deal with on top of what i've seen so far are related to the sets creation. in src/distrib/sets/lists/comp you'll find all these files you're looking at not installing now. they'll need to be marked "obsolete" in here.
you could just reference either a tech-kern or a current-users post if you want some permanent link, but i don't think it really matters too much. searches will likely find the commit log itself, which should also explain everything :-) thanks for looking at this. we've gotten better since early days with these sorts of issues, but there are still a lot of headers that are installed for no good reason but no one has had the chance/motivation to clean them up yet. .mrg.
