Personally I think your overflow baffles (the 3 where the water goes over them) are too high. You have very little room for extra water when the return pump stops. Probable sump overflow situation. Also your slimmer will need a serious lift to get to the proper water level. My sump is barely 1/2 full in normal conditions.

Thanks for the answers! Super helpful. That picture isn't mine (Google) it's just the general layout I wanted my baffles. Mine will not be that high.
One last question, do I need to worry about calculating GPH
and how much I'm going to lose?
That's been the part keeping me from getting this done. (Never done this before) I'm worried that I may have too much flow and not enough power to bring it back and my sump will overflow or too little flow and too much power and my display will overflow? Will this work itself out?
Do I need to be super precise and calculate this to the dime (I don't even know how I'd do that lol) or is a "general idea" of how much GPH
sufficient? And how do I even figure out my GPH
Am I overthinking this? Lol
