It definitely would make sense. Lilligant is part of nature like fairies and has the beautiful, fairy princess design theme. The 4x weakness to poison would be annoying since grass already has a quite a few weakness, on the other hand she would lose the bug weakness and become a Dragon slayer, even fighting and dark types would fall to her mercy so it is probably worth it in the long run. Edit: Maybe Lilligant will get a mega and the chance to achieve fairyhood? I would like to see mega evolution not thrown to curb.
