Yeah, as I wrote that I thought of all the intrigue and power play that would likely go along with. The only way it could possibly work semi peacefully is that Dooku was the mos senior in the line of peerage and his reclaiming his title put him at the top of the order. Any enemies he would silence quickly and efficiently.I can see a scenario where that "reclaiming" involved a lot of stabbing, maybe some poison, and one or two tragic accidents when people brutally and mysteriously cut their own heads off while shaving.
I mean he'd been a Jedi for going on 80 years. Clearly others would have inherited what would otherwise have been his, and historically speaking, aristocrats aren't very quick to give up power and wealth they feel they're entitled to. So there was probably a long line of second cousins, great nieces and nephews standing in his way.
Ooof, yeah, this is dark.
