A question like this has been asked before, but on gen 1 pokemon that now have mega evolutions, there aren't any new move sets for them. So this is sort of saying there could be some new questions for pokemon like these, or people should post new or mega move set suggestions, because this was meant to happen, but it hasn't.
Mega Evolution movesets should just be posted on the Pokemon's moveset page. If people have moveset suggestions for Mega Kangaskhan, for example, they will post it on Kangaskhan's moveset page and label it as such, which people have been doing.
