Vegeta: i think we he can go ssj2 he could have and suicide attack like when he fought buu in buu saga and killed himself and the higher the power bigger the blast
SSJ4: I think that you could throw a fake moon into the sky (like in sayin saga) and then you would go golden ozzuro (big money) for like 30-40 secs then shrink down to SSJ4
Goku: When he is able to reach SSJ4 he should be able to do Dragon fist
Misc: you would have to find the scouter and you could pick up sayin armour
Just all a thought please tell me what you think
