Ok - re-reading your email, I misunderstood what you were trying to do.  I think
what you're describing could be made to work.  It would just take some effort to
ensure any final solution was well designed and something we wanted long term
though, and even then I'm not completely sure about it.  It would require one
driver knowing the internal structures and implementation of a separate driver
that may be difficult to maintain.
