just curious to see if anyone has tried this type of filtration, with water taken into a canister and then the output going through a wetdry then back into the tank.

My dentist has a canister filter that drains through an undergravel filter (The tank bottom is drilled). I see no downside to having a canister filter drain into a wet dry other than making sure water pumps back into the tank at a similar rate as the canister filter.
Nice idea.
Bad idea. Wet/dry filters work with gravity drains with the water level constant in the tank. Canisters work on siphon drains with the water volume being constant in the canister. There's no way to regulate the sump level with 2 pumps working against each other. Either run the canister intake/outlet in the sump or run the 2 filters separately.

True, but he could just use the canister filter with no power and let gravity do it's thing. Makes a pretty good pre filter.

That just makes the canister into a prefilter that will clog and have to be disassembled for cleaning. May as well use an open prefilter with coarse sponge covers on the drain pipes. Then, nothing needs to be shut down or opened for periodic cleaning. If the additional bio-chamber is what's needed, use a right-size sump from the beginning.
I'm all for improvising and redesigning equipment. But, the end result should always be an improvement either in design, functionality, and/or ease in maintenance.
You could have a bio chamber above the tank. This way you use the canister in the normal fashion, but run the return up to the top of the bio chamber, then the water drains from the bio chamber and back into the tank. This way you don't have to try and use 2 pumps. But you do lose some flow rate from the pump becuase of the high head.
This is kinda how I seed bio balls for my w/d filters. I just use a bucket with a cheap bulkhead (hole with a peice pvc pipe glued in) that drains back into the tank. I have yet to have this fail on me.
