Food for thought...4 way switches will indeed help you reverse your motors but there is a cost. Even stripped down they are relatively heavy and also one must consider the rate of the descent and the endpoint velocity as your bot strikes the base platform. Not sure what the effect on the field element will be. Has anyone tested a motor aided return to the base platform?
