Here is a wiki link that has more themes to think about: http://leagueoflegends.wikia.com/wiki/Champion_skin/Skin_themes

I don't think Lookalike team would make any change, it doesn't matter at all and force it may make a bad comp team with wired champions and role combination.

If you still want to make it, you can check here for a type of skins like Star guardians and so
