Gohan Ultimate would have gone to the Future of Trunks?

[SIAD]

What would have happened if Future Trunks instead of having traveled a second time to the Main Time Line to the year 767, would have traveled to the year 774 just after Goku ended with Majin Boo and Gohan decides to travel to the Future Timeline Trunks and stay to live there?

  I say that Gohan Ultimate by staying to live in the Future Trunks Timeline, first kills the Androids and kills Cell. Then kill Babidi and Dabura. Everything is peace until Goku Black appears.
