I don't think you need to remove them but if you want to avoid the issue of monsters entering them and unequal stuff between Chip and Melinda's characteristics, you should make the first transmogrifer a one time use thing and maybe include a hint stating players can choose to play the level as Chip or Melinda and either or wouldn't make much of a difference. Whether you want to do this with every level that offers this option is up to you though. However, if some of your levels include stuff like ice Chip must slide on, a female only section for Melinda, etc. then I'd maybe remove the transmogrifer entirely to avoid confusion for the players.

In all honestly, the fact you include a transmogrifer at the start of your levels makes your set very unique. I don't believe any other CC2 level designer would include an option like that for players so it's quite nice you do that.
