On the Maestro D' and the Skinner: the Maestro D' makes an excellent "prestige class" for a Skinner who's become an "ascended performer" and obtained their own establishment. I was actually leaning towards that with my own old Skinner before the campaign got canned (sadness).
(I will admit that the class-changing rules as written can be, uh, problematic, though. It basically means that moving from a class with a lot of intrinsics to one with a lot of extrinsics is awesome, but that if you're a class with a lot of extrinsics and you try to pick up one with intrinsics, suddenly you're screwed and damn near starting over.)
Also, a cult leader and a warrior fighting for a better tomorrow are two entirely different things. They can merge, yes, much as any two archetypes can--the Touchstone actually does have an improvement that gives them followers and the fortunes move. Think of it this way: the Hocus is not only supernaturally oriented, but a leader (and they may even be one more interested in power and exploiting their cult than their stated goals), whereas the Touchstone is more naturally oriented (as observed), and while they absolutely can lead and especially inspire, they do it from the front lines: they are hero first and leader second, and all that. Though you seem like you might already have that down, so I'll reiterate they absolutely can become the same thing: it's just a matter of things like getting cross-class moves, finding ways to bolster a Hocus's Hard and a Touchstone's Weird, and probably going on to change playbooks when one gets the opportunity.
