Maybe in the Legends universe, but definitely not in Canon. A white Lightsaber with Obi-Wan’s clone armor would be cool though….

Maybe. It would be an interesting story as to how he got it, like did he steal an Inquisitor’s lightsaber like Ahsoka and purified it or did he just find a random white lightsaber somewhere etc.

Maybe though I prefer his Blue blade

Yeah sure it fit Ashoka
