Unless I misunderstand your intent, this should be easily accomplished
using current builds of OVS. Models similar to what you describe are
already in use in some OpenStack environments, if I'm not mistaken.

- Create two bridges---one to use with the controller, and one to use
for L2 forwarding over physical interfaces. For example, you might call
them "br-int" (integration bridge) and "br-phy" (for physical interfaces).

- Connect "br-int" to the controller.

- Configure "br-phy" with appropriate physical interfaces, bonds, etc.

This should accomplish what you're seeking.

Hope this helps,
