I'm thinking about that myself. I can see them swapping out the tank for another jet even to help evoke Star Saber's alt mode better and have his Titan master represent his different gimmicks. Like for the TM body it can represent his brainmaster then in head mode it'll be Saber then once you plug the TM into the body the helmet flips down to make Star Saber. That alone actually makes him fit right into the TR line in that respect and it would be a huge missed potential not to include him since at this point we already got Liokaiser,and Sky Shadow incoming and with the rumored Deathsaurus in the future. It wouldn't make sense if we just have the three Decepticons form Victory and not include the main hero especially that he has a role in IDW and is still alive for him to make a big comeback.
