I think it can be a stretch to try to import trump card meanings directly to the minor cards. Their connection is primarily numerological. The number Six is a number of balance and harmony. But the Lovers is associated with Air (Gemini) and the 6 of Cups with Water (Sun in Scorpio). The kids (I don't see a dwarf, necessarily) in the latter card don't look like they have a Scorpionic thought in their heads. There is too much sweetness there, while the couple in the Lovers seem more conflicted. The Lovers can mean a parting of the ways as readily as a liaison (the Hebrew letter for the card means "sword" and the concept can have a dual association: to cleave to something means to "adhere firmly and closely or loyally and unwaveringly," while to cleave something means to "divide by or as if by a cutting blow"), while the 6 of Cups seems more about the pleasure of the moment.
