It sounds like a reasonable approach.  If you were doing intermittent
manual imports, you could use 'add --file-ids-from', though that may
not handle them being at different points in the tree.

Perhaps the best thing is to work out what cvs conversion tool you are
going to use, and go from there.  I don't know of any that has built
in code to handle this (but I may just not know of it.)
