Having Boba on the show would be jumping the shark. I really hope they don't go that route. They don't need to. Unlike TFA and RoS they have found the perfect balance between original content and fan service.
I dont really think it would. Clone Wars basically set up the Fetts as impostor Mandalorians and Mandalorians not being super happy about that. It's not a major thread or anything, but theres actual connective tissue there that allows it to not be a blatant shoe horn.
