Yeah that was my question too. People seemed to think it should be more post-lightning deformation Emperor Palpatine than Senator Palpatine. I could try the other way though!
I think if the implication is that the Palpatine we see is one of the clones then the clone has to be unwrinkled, like the Palp in the film.
Is there anyway to make the bodies smaller? Could be tricky but Snoke is a much bigger guy.
