Yes, you could put your return pump in a seperate container in the sump, the water level will operate above the top of the container. If the siphon breaks the return will pump the water down to the level of the container and only that which is in the container (mines like 2 gallons or so). This keeps all the water from being pumped out of the sump, also, the heater and skimmer still have static water to keep operating normally. The only difference from a float is that the return pump will eventually burn out. I've tested the level in mine (by breaking the siphon) with enough distance from the waterline to the top of the tank, you should be able to clear out the small container and not overflow the tank too much with a siphon break. Adding more evaporating water to the sump marked by your waterline will make it go over but at least it doesn't pump the whole sump.
