Question about IM EXT Sump Media Chamber

[towels]

Looking to make some adjustments to the filter media chamber in my IM ext 75G - 39G sump. There is a black piece that has 3 large holes for mounting the media cups or filter socks in that rests on a rim in the sump. I'm basically looking to replace this piece with one thats fitted for filter rollers (instead of 3 holes). I was curious if anyone knew of a company that might make different variations of this piece or if they had any recommendations as to where I could possibly get this made. I will add a picture of the exact piece later but I've added an attachment referencing the area the piece is located and what I had in mind.

This would be for 1 - 2 Red Seas nano filter rollers. In the event I could get this made, how do you think it'd perform? Of course, the flow entrances on the filter rollers would be facing the flow/heater chamber (highlighted in green)

Thanks
