need help with design canister/refug

[Polscot]

hey, i recently bought a fluval 105 for my edge, now heres the question, would it be possible to cut off the bottom of the fluval, then take a 10g tank seal the lid with only a small hole on top, then silicone/fuse the bottom of the canister to the tank, essentially making the whole tank part of the canister, i wanted to know if this would actually work, like would the pump be strong enough, my goal is to make a simple refugium for my edge....

any thoughts are appreciated
