I'm not sure your presumptions about query performance for multiple taxonomies are correct.
WP3.4 is making some changes in this area that I haven't looked at, but a I think a taxonomy query with multiple terms is same whether or not those terms are in the same taxonomy. By the time the MySQL is generated, it's just a bunch of term_taxonomy_ids, whether those represent category terms or some mix of taxonomies is irrelevant.
