skimmer for cramped space

[fishdaddy3]

hellllo fellow reefers!! after 4 years of having taken down my 120 gallon reef and running only 2 33 gallon reef tanks i finally put up a 90 gallon. Damn big tanks look good!!! Being so excited to set this thing up, i didn't realize that I don't have enough clearance between the top of the sump and the bottom of the stand to fit a skimmer in. I don't want a hang on skimmer so I was wondering if I can submerse the pump of a skimmer in the sump and then have the skimmer beside the sump... Help a brother out please.
