Sorry for the late response, it has been a somewhat busy week for me. Again, feel free to ask/quote directly me and I'll answer your what if questions, probably even longer if I find it interesting.
Steven Bloodriver wrote:1) Thank you very much, Hunduel!
2) What if following the Cell Games, but before Future Trunks' departure from the present, Vegeta and Gohan had decided to accompany Future Trunks to the future?
3) What if in the battle between Super Saiyan 3 Goku and Kid Buu, in the very beginning of their confrontation on the Sacred Planet of the Supreme Kais, Goku had his tail returned to him?
1. No problem.
2. I think Vegeta would have destroyed Android 18 just to make his ego feel better, and would have an interesting meeting with Future Bulma, while Gohan would probably meet with Future Chi-Chi too to make her feel better. However, I wonder if them travelling back would cause a butterfly effect and they may have to fight with someone too (something similar to Super Android 13 could have happened, for example).
3. I'm not an expert at GT, but if I remember well the tail allowed him to control his ki and energy better, so he'd probably use SSJ3 in a more consistent way without losing too much energy just at keeping the form up. I'm not sure if it allowed him to defeat Kid Buu, but would have a much bigger chance for sure.

How would Toriyama find a way for Goku and the others to defeat powerful enemies like Freeza, Cell, Buu and Zamasu? I could see Toriyama having Piccolo learn Kaioken seeing how he did train on North Kaio's planet.
Then Toriyama would have introduced Tag Team attacks, where two (or more) people have to perform two specific attacks to combine them into a much bigger attack. For example, Goku and Vegeta are standing next to each other so closely like they do in the Return of Cooler movie, and if Goku performs a Kamehameha Wave, while Vegeta doing the Final Flash, it could have been combined into a Final Kamehameha.

I actually think Ultra Instinct is not based on multipliers but it is a "fixed amount of level" they provide. That's why the gap between SSBKKx20 and UI can be so huge.

He could only win if he did it while doing the IT Kamehameha, because it would probably exhaust him too much.
Dragon Ball Gus wrote:What if Gohan got involved in the Future Trunks Arc? How strong would he have become?
He could probably be ToP level by that time if he'd trained enough. But he's still far beyond the God tiers, though.

2) What if Gohan's rage boosts were permanent?
3) What if Goten had learned Ultra Instinct when Super Buu had killed Chi-Chi and became immune to being absorbed by the Majin?
4) What if Pan had went with Goku and Uub at the end of Dragon Ball Z? How would this have changed Dragon Ball GT?
1. Then Grandpa Gohan would be alive and would be a much bigger motivation for him than Roshi was. The dynamic between the two olds could have been more interesting too. Also one of the saiyans killing Grandpa Gohan could have trigger something inside Goku, like a canon Pseudo Super Saiyan transformation.
2. Like a Zenkai boost? He'd probably be extremely relevant in the earlier sagas, like being able to beat Raditz (even if Goku still dies somehow), and more importantly, defeat Nappa without a problem. The Namek Saga would be the first one where he'd have been a background character, as his boost would still be not enough to beat the Ginyu Force.
3. In my interpretation, he'd probably be able to beat him easily. However, even just the ability of not being able to be absorbed could have been really interesting, as it opens the possible Potara fusion of Goku and Goten.
4. Again, not a GT expert, but she'd probably still not be relevant enough... but he'd achieve SS for sure.

Then we'd have a literal Suicide Squad

In this case, he'd be a Goku clone. If anything, Goku's the greatest example of low potential but a huge force of will and incredible amount of training.
