Roller mat for innovative marine sump

[The Salty Tank]

So I'm interested in purchasing a innovative marine EXT. 200 gallon tank. The real big hesitation is the sump that it comes with doesn't have room for a Red Sea reef mat roller 1200. I'm done with filter socks and filter floss. Both my other tanks have rollers and they're great. Has anyone on here had success putting a roller mat in one of these sumps? What kind of modifications did you have to do? I do not want to own a Red Sea tank. I kind of wish innovative Marine would sell their aquarium without the sump and I could just make my own. I appreciate any help and I appreciate reef 2 reef
