Your might be able to use add_rewrite_rule() although it may conflict with other URLs, not sure. I rarely use the "official" approach because it requires rewrite rules to be refreshed.

What I like to use is the 'parse_request' hook at modify $wp->query_args.  You can find an example that should meeting your needs here and it can give you a little insight into what URLs translate to internally:
