If you can't do PBR, could you break the stack of switches up? That would give you two unique routing instances. You could hang the special subnet off of a specific C2/3 and have the default GW point where you want it. Then have the remaining C2/3s peer with the lone C2/3 so you wouldn't have any reach-ability issues.
Sounds like a crazy idea, huh?

It looks like I will be able to do the N7 but the C Stack doesn't support it.

I don’t know what rev PBR came out for Ns.

I have all of my hosts directed out to my Internet connection via a default route but need to redirect hosts from one particular subnet out another router heading a different direction. Is this possible?
