Response to Doug Batonsly
I prefer Boba. Now I know Jango and Boba are two very similar people, but I think there are some things about Boba that are cooler. His armor, for example, used to show how experienced of a warrior he was (you know, before he repainted it). Also, I admire his feats in hunting and survival.
They would do very well on Remnant, the both of them. As for who they work with, all that matters is who pays them more. Boba gives his allegiance to no one, and I think the same can be said for Jango. At the end of the day, they're bounty hunters. All they care about is earning their rewards.
I would love to see some of the characters you mentioned. I doubt Starkiller could make an appearance, but Montross and Jaster would be exciting to see.
The 501st would work well with Ironwood and the Ace-Ops. Together, they would be a perfect army. I understand why you might think troops like Jesse and Fives would go behind their backs, but they did this for two reasons: Krell didn't listen to their logic, and Krell had a lot of the clones kill each other. Now Ironwood probably wouldn't listen if they wanted to save Mantle, but Ironwood wouldn't send his own soldiers to fight and kill each other.
