yes, as I see it, the two biggest problems would be:
1. failure of the overflow with the subsequent overflow of the display by the system pump pumping the water out of the sump 2. failure of the system pump with the subsequent overflow of the sump with display tank water If the sump has large enough void space and float switches are installed on the display to turn off the sytem pump, this should elimiate (or at least reduce the chances of) both possibilities, right? Oh, the dimensions of the tank are 36X18X20. Thanks for the comments so far! Keep 'em coming!

The DT will never overflow if designed right. Nor the sump

Emergency over flow is a must, float switches and such for pump shut down are nice, but you would not really need them with a emergency overflow set-up. As for a sump over flow(more likely - power outage etc ) such as for when a pump shuts down and the return line back siphons, a margin of available empty space is required to handle this - here a link for a rough estimate
http://www.reefcentral.com/index.php/sump-volume - you could also add a check valve in the return line to prevent back siphoning or add a bleed hole in the return outlet just below your water line in the tank. Just a few quick idea's.
