I think you could get better value for money if you picked measurehead instead of Titus. I also think you're sleeping on Evrart. He has his tendencies as he is now, but given the prompt he would not have those tendencies, since hed have yours instead.
My biggest issue with him is how he does urban planning, everything else seems like him just using the tools available to him. He's only a syndicalist because the unions are one of the few organisations still standing. The bureaucrat part of him I dont really see. Hes as much a bureaucrat as Joyce or the Sunday Friend, Papers are just one of the tools he uses. Its pretty clear he does so much more and is the core of planning for Titus and the rest of the Union.

Titus on the other hand seems kind of unreliable to me. Much more invested in being a big authority macho guy than the actual ideology of it all. He's a good enough guy, but not someone id rely on for anything more than being a brute. I think measurehead would be better, since he seems to dedicate himself entirely to his ideology.

I did not think about soona though. I'd forgotten her. She could be cool.
