What about two short blades and beskar gauntlets to block lightsaber attacks and get close. Maybe even a short lightsaber built into a gauntlet. I hate this analogy but it's the best way to describe it, but think assasins creed mixed with jedi.
I think it would be interesting to have a small order of said "jedi". But make them amber jedi (use light and dark). They would be like Boba Fett and his Mandalorians. You wouldn't know whether to like them or hate them.
