Drilled sump for overflow drain:
This is a very cool idea, think I will attempt it myself. I see a possible problem though, correct me if I'm wrong.
Say you are out of the house for a couple of hours, and there is a power failure. The main pump shuts down and the water overflowing from the tank and backflowing from the returns (if you don't have a check valve) will cause the water to rise in the sump. This excess water will drain out the drip overflow in the sump. Then when the power returns won't the pump suck air and burn up?

yes, that's correct, i'm actually looking for a normally closed solenoid to put in that line that will shut a valve in the case of a failure.
Good call.

Lawn sprinkler valve, normally closed and can be powered by a small wall wart transformer.
Are they rated for continuous duty? The ones I'm finding arent.Lawn sprinkler valve, normally closed and can be powered by a small wall wart transformer.
Don't you want the valve off and the timer to turn it on ? That's what sprinkler systems do, and the valves are about $20 for the larger ones.Are they rated for continuous duty? The ones I'm finding arent.
