I mean if they keep the mandate I feel as if they need to use the characters that they're given.  I mean if they wanna go with a model they probably already have a base for Connor and Caitlin could be an option!  But if they also want to use newer CGI characters any of the experimental engines or the Steel Mill engines from Journey beyond Sodor, that might just be because I am biased and would easily buy a hurricane model in a heartbeat! And if they want to keep adding to their narrow gauge line while also using characters that were introduced in CGI they could go With characters like Luke or Millie, really they've got a lot of wild options if they keep the mandate, but i understand why people want them to get rid of it.  Oh and adding whiff to the lineup would be cool, he's somehow still relevant I guess?
