Dragon Ball GT Shadow Dragon arc would've been so much cooler if each fighter got a chance to fight their own dragon. Like the fighters all split into groups of 2-3 and go off to find and fight a Shadow Dragon and retrieve the dragon balls. Especially if they fight a dragon that is tied to them in some way.
Goku goes with Pan and they fight Rage Shenron, who's tied to the wish to revive Goku after his fight with Raditz.
Vegeta, along with Bulma who tags along cause its Bulma, fight Naturon Shenron who is tied to the wish of reviving all the people Majin Vegeta killed. It would've been a good character moment for Vegeta to reflect on his past and even Bulma to an extent since I believe she was the one who made the wish. This confrontation also would've been a better build up to Vegeta unlocking SSJ4, maybe Naturon captures Bulma and Vegeta transforms for the first time in order to save his wife.
Gohan and even Videl can join him (cause she deserves more chances to kick ass instead of being benched to the sidelines) and they fight Nuova Shenron who is the four star dragon which is an important heirloom in Gohan's family but also the wish Nuova is tied to is King Piccolo's wish for youth, tying into Gohan's friendship with Piccolo.
Uub could fight Eis Shenron because he's tied into the wish to have everyone forget about Majin Buu and his evil deeds. He just deserved more screen time after all that build up for his character.
Maybe Trunks and Goten fight Haze Shenron, tied to the wish to revive Bora, a call back to the very first series and parallel to the adventures Trunks' mom and Goten's dad were on together back in the early days of dragon ball.
And for fun, Oceanus Shenron targets Oolang because she's the underwear wish that he made and maybe it's Yamcha and Roshi who have to fight her. Maybe also Krillin and Android 18 get involved (I know Krillin is dead by that point but with some rewriting he could just be there to help out). Plus she's an ocean themed dragon, the fight can take place on Roshi's island that is literally surrounded by the ocean!!
And then by the end, everyone comes together to take on Omega Shenron, the finale dragon.
