I think this can be done by beginning a transaction based on the
working directory's root revision, opening nodes from various other
revisions and plunking them into place with svn_fs_copy (which won't
actually do any copying), calling `svn_fs_dir_delta' to get the delta,
and then calling `svn_fs_abort_txn' to throw away the copy of the
working directory's base tree.
