IMO, I don't think that Lily was going to close the show or wear the bubble outfit. I think that the pictures of her in the bubble outfit were a red herring or, at most, perhaps VS was considering her for the dress alone and Chanel was going to wear a different dress, bikini or whatever along with the bubble wings and gun to close the show. Even though Lily seems like she can be fun in her own way, I cannot see her even being considered for walking down a runway shooting off a bubble gun.
