Long term who knows how the story goes, but as of right now they're using Morph to fulfill action cameos rather than have these characters have full-fledged significant character/storyline time. Morph isn't a staple X-Men character and definitely wasn't a Blue/Gold team member, but he has shapeshifted into some of them and used their powers.
I'm guessing Juggernaut won't be a significant part of these two seasons, neither will Psylocke, Colossus nor Quicksilver if that's the case. Now he did morph into Spiral and she had some quick appearances so that was cool.
