Agree with you except for the redo part. I think it's too late and redundant now. But there are good fanfictions out there treating this subject.Gohan should have a completely different involvement. More involved than Goku. I think Gohan should have been instead of Goku right after he died before the before cell's death. Goku should have never comeback after cell. And I think the whole cell scenario with the tournament and all should had been done differently. Goku should have died and that is it. He never should have appeared again. Gohan's story line should have been developed further. And think they can still redo it. I would be better for me if they took Goku out of Dragonball like Akiro wanted. Goku should die and Gohan should be better. Together with the others Trunks and Vegeta.
