Absolutely, although two things to be aware of. First, a canister does not replace a sump in terms of extra water volume since it adds so little, so you will need to keep that in mind when stocking the tank (it will behave more like a sump-less tank when new). Second, to avoid crud buildup problems in the canister you'll want to prefilter the intake. Just wrap some sponge or bit of filter pad around the intake to keep food in the tank where stuff can eat it. You should then clean the prefilter or change it (depending on the material really) with your regular weekly maintenance.
If you read around about canisters in marine on the web or talk to random people in the hobby, you will encounter a lot of hate for canister filters. They carry the "nitrate factory" myth with them, which is a situation that happens when you don't manage them up properly, specifically failure to prefilter and maintain them when they obviously need it. Canisters will turn into a "nitrate factory" when food and other large stuff gets sucked away and trapped where it decays, and it often happens with overfeeding (having to add more food because it gets sucked away). But, it is possible to be smart about it and canisters can work great when you manage them correctly, particularly for tanks that don't have built-in compartments for storing chemical media and/or extra LR. I have two canisters on my similarly-sized tank: one for chemical media since it's small and one for LR rubble. I maintain the small one at each WC, changing the media as needed. The large one I only had to check regularly when it was new and now I only look at it out of curiosity; it never slows down or clogs. The reason for that is that canisters that are for extra LR eventually develop their own internal fauna of worms and tiny Crustaceans that will help keep them clean and flowing well (but it takes time to develop and also won't happen so much in chemical media-only canisters).
