Recruited generals and client rulers

[QuintusSertorius]

Something I'm not entirely clear on with the system in 1.2. Can a recruited general or client ruler change status after their second turn?

As in if you leave a recruited general in a settlement on their second turn, and they become a client ruler, are they forever thus?

Similarly, if you take them campaigning, can they no longer become a client ruler of a newly-conquered settlement?

I'm wondering if I recruit a general to take a settlement, I won't then be able to use them as the client ruler of a type IV government.

A recruited general can turn into a client ruler, if you let him build a type iv government in the newly conquered settlement, if I'm not mistaken

[Taedius]

Yes, he'll change. He will get the impostor trait before the lvl4 is built though.

Has anyone seen the reverse happen, i.e. a client ruler turn into a recruited general? I've transplanted a client ruler across half the map, and I don't recall him ever changing into a recruited general on the 3-year journey. (I gave away his first city in a peace deal, then exiled him to run a Black Sea city - every winter he'd get sick, and the fleet he was on would have a movement allowance of one...)

Nope, it's not possible without using the give_trait command since there's no trigger that reverts the Client Ruler trait.
