I'm not usually one for crossovers but I am going to try this. An idea of sorts may have come to me last night.

Here is what you need to indicate when you sign-up:
1. Series you are crossing over with.He-Man
2. Character(s) from #1 that you are picking. The Sorceress
3. Featured guest LnC character(s) you are going to pair #2 with. A Young Clark and possibly his parents as well.
