perhaps i'm not understanding what you mean but you can apply a
rib-group to direct routes...

routing-options {
    interface-routes {
	rib-group inet <name>;
    }
}

This can be the same rib-group that you use w/ other protocols to leak
routes between instances...

Still for the overlapping VPN scenario i believe auto-export gives you
the same functionality w/ much less configuration.

The difference between the two is that rib-groups are applied to
routes received by a protocol before that route is added to the
routing-table and thus before path selection.

auto-export is applied after path selection and only "exports" the
active path.
