Could this principle be used to make a reactionless drive for spacecraft? I would assume it would only be effective in an absurdly deep gravity well, like righ

  Sort of, but not really. This is like reorienting yourself in midair by waving your arms in that it doesn't change your velocity, just your position. So while something like an ion engine can get away with absurdly low accelerations because they build up to large values over time, this gives you an extremely low velocity with no way to increase it. And in space with a high enough degree of curvature for this to work, you need to be moving at a very high speed in the first place to not immediately fall into the source of the curvature.
