If you go the RPC route, you will have access to a rogue, but I didn't care much for him myself.
There's also the possiblity of dual-classing one of your characters at some point. Then you could keep your party closer to your original build perhaps. There are some spells your casters can use as well(Knock Knock and Divine Traps)that might help out.
Best of luck : )
