Well, I created this topic for all duellers who would have a -possible- legal Bluelike form. Minato, FES Aigis, and Souji definitely have Bluelike forms that are legal under fairly normal interps.
I suppose there are some currently-ranked duellers who could be Bluelike under fairly unusual interps that I don't have listed yet, but I think I've got most of the ones from ranked games...
