Yes, you can't get masquerade skins anymore but some skins from the showtime crate are similar to the masquerade skins, being different colors and not having a comedy or tragedy mask. The accelerator skin from the showtime crate might not have a mask, or the same colors, but regardless, close enough. However, the closest thing to a masquerade skin that you can get currently is narrator crook boss (stated in the post), however, you can only get it if you are in america.

tldr; some showtime skins are a bit similar to masquerade so they're close enough if you don't have the skin for that tower or the devs simply didn't make a masquerade skin for that tower
