I'm not begging for this and am far from anticipating it, but would like to see it happen. I am also aware that Separatists and Jedi should come first, I'M JUST SAYING.
Tuskens only have three characters. Three characters does not a full faction make. These fellas play a bigger role than nightsisters in my opinion, so I think they could get should similar love (killing Anakin's mother, causing Old Ben to show himself to Luke, etc.)
They need two more characters to be a full squad. You would have to get outside of canon a bit to make them anyone of note, but there wasn't a shaman in the movies either.
A'sharad Hett is a Jedi-turned-Tusken from the Outlander comics that was also referenced in the Kenobi legends novel. That seems like a good character to add some viability to a strong Tusken squad. A'Yark (Plug Eye) is another noteworthy Tusken from Kenobi. Tuskens aren't powerful, but Ewok-like synergies would make some sense here.
Just something to think about!
