Mars has such moons; Venus doesn't.
1. Electric motors in space still need reaction mass. So whether its some generationally improved ion engine, chemical thrust, or even a buncha aerosol cans glued to the wings, you're still needing fuel mass.

2. I wouldn't put too much stock in momentum stealing from Martian moons. They're not all that gravitationally impressive, otherwise we'd be using them already for satellite capture.
