You can build your desired setup with the two VR but you will need to have a pair of interfaces put in the two VR and loop those two tegether in this configuration. There are some internal connection methods but these are generally for leaking routes not treating an interface with a filter.
Basically assign interfaces to the VR and then treat those interfaces as if you had completly separate routers.
