Have you looked at the way the Handel storage stuff works? That already
supports both DBIC and RDBO so might be an interesting start.

Do you have any thoughts on how to paper over DBIC's ability to chain searches
vs. the lack of that feature in RDBO? I know most RDBO users don't feel
they're deprived not having it but DBIC users are generally fairly addicted :)
