Sump help

I'm thinking you could use the trapezoid chamber for your drain inlet and skimmer chamber, and have it go under the divider to one side of the back half which would become your fuge
Seal off the bottom of the trapezoid to the 'other' back half chamber, and use it for the return pump, utilizing the overflow of that center baffle
This will give you a decent bubble trap as well
And no adding extra panels, just a quick strip to seal off half of that under-pass
