I'm in the process of setting up a sump right now, but before I had one I just had my Rena XP2. I got a plastic drawer, cut a drain, filled it up with bio balls, then cute a hole in the top that I could stick my spray bar into. Then I hid the entire thing in my hood. It worked great. You could try and work something out like that, either using the return from your sump to feed a small top mounted wet dry filter, or using the canister to go right from the tank to the wet dry, but I don't see a realistic way to hook all three together.
