I'm sorry but I have NO idea what you are trying to do with that tank design.
As for a pump instead of an overflow, I think you are missing part of the reason for an overflow and sump. It is to get rid of an hide things like pumps, skimmers, and heaters so you don't see them. Why would you want a pump in your tank? Also an overflow skims any surface scum off of the top of your tank and a pump is NOT going to do that. 3rd, what happens to your tank level and sump when you lose power and a vacuum sucks most of the water out of your tank into the sump.
Stick with the proven methods, you will have better luck and a safer tank...

can you? yes
should you? NO!!
the reason an overflow and return pump works is that whatever volume of water that the return pump pumps is the same volume of water that the overflow flows.
if you are using two pumps, you have to have them dialed in perfectly to be pumping the same amount of water or one tank or the other will overflow. it is very dangerous even if you get it dialed in because if one pump gets blocked or slows down, the other will overflow that tank.

DO NOT do that. as scrager stated, the point of an overflow is to equalize the volume in and out. it would be near impossible to get the 2 pumps pumping at the same rate, and furthermore, if the retrn pump shut down you can pump all the water out of your display tank.
