I think that, as others have said, you could achieve this effect with mq
by loading all the patches into mq and then using mq's features to merge
patches.

Alternatively, you can just use 'hg diff -g -r foo -r bar' to export the
changes you want and recommit manually on a different branch.

My own preference is to keep the old branch around and merge the two
together later.  (You'll have conflicts, but they should all
auto-resolve)  That way you still have the original history.
