Just take a look at what your car starter motor takes to switch about 200A...and see how its dine.

IMHO the weight disadvantages of a mechanical switch outweigh the efficeincy loss on a MOSFET, and frankly, a brushed ESC is not much more expensive than a servo and a relaible switch, and receiver battery.
