No. I don't want a bad version of my favorite character. I really like Jade but I'd rather not have her if they cramp Kitaana/Mileena/Jade into 1 character. Either it's complete/fully polished character or nothing at all.
However, if by "bad" it means that the character is mid/low tier that's still acceptable to me. Again, Jade in Mk9 is a good example. She being low tier wasn't great but she was still fun to play with.
