Maybe have the True Mandalorians being, while not broken and scattered like in the regular canon, still thin in numbers and struggling to gain legitimacy in the galaxy, especially in their home systems, after years of civil war with Death Watch? Jango is Mandalore and heading a force of maybe a hundred or two hundred at most. Maybe Death Watch's plot at Galidraan didn't even take off if, say, Dooku were to get suspicious and do a little poking around? If that's amenable to [@Burning Kitty].
