I'm not so sure about having traffic leave through the router via which it arrived. You have no way of knowing that unless you were to tag packets or track flows, keeping state... If you wish to force packets through a router, you might consider tagging learned routes with a community corresponding to the router that learned the route. On the edge router you could force next hop according to community. Again, though, these are gross and messy. I'm not sure if hacks will make your situation better or worse.
