Cross a chinese lantern with a tomato...is it possible?

What would happen if I got a q tip and swiped the pollen off of the floweriing tomato plant and Physalis Alkekengi(chinese lantern) and rubbed the opposite pollen on the other flowering pods...Basically put th epollen from the tomato on the chinese lantern and vice versa??? What would happen? Im asking this because th etwo plants are closely related.
