Not really. It would be another Jetfire drama situation, likely. You know how that played out.
It would have been an alternate timeline
I mean its already, mostly, canon (I believe canon to TFA but not Ben 10), that at some point the TFA universe and the Ben 10 Universe came in contact for a small period of time (explanation on why Khyber has some Transformers themed trophies)
What do you think?
