skimmers are "self leveling" meaning they have outlets designed to maintain a certain water level in the skimmer body. Either way, your skimmer will need somewhere to dump. If you try to push the water back up to the tank, I'm thinking it's going to pour out around or through the collection cup.
You can get a pressure switch that would regulate the water level in your tank. If you set up a sump with one of these switches in the main tank, it would be as close to disaster proof as a sump can be. Correctly adjusted, the switch would shut off the circulation pump before the tank overflowed in the event of a broken siphon.
