Sump help

[freeze]

So I need a little sump help. It's a 92 gallon corner bowfront and this is the sump that canoe with it. Got it for a steal but now trying to figure out plumbing and sump layout. Here is the sump.


I have an swc 160 cone skimmer for it. It's fits in all the chambers.

Here is the issue. As seen in the front right chamber there is a section at the bottom that is open. I want to have a camber with my skimmer in it coming from tank, a fuge and then a return or course. The basics. Just trying to figure out how to lay it out. I can do some lexan and silo coming if necessary which I am thinking it most likely will. My return pump is an eheim 1262. Any help or suggestions would be appreciated.
