Dropping the titles also works. We've already sort-of implemented such type of voluntary work with the "embassies". Trusting our members, even the new ones, to do the right thing is important to show the collective can grow beyond the tight knit roots. Any "transgression" by any type of volunteers can be discussed and dealt with by the Ecclesia as a whole, there's no need to have a chief-this chief-that.
Regarding citizenry, if I'm not mistaken many people that intervene here can change the group (add the citizenship banner) for new members, imo it's easier to accept everyone without background/security check, and that doesn't need to be done before being accepted as citizen, it could as well be done after anyone is accepted as citizen, if there's a problem with anyone registering I'm pretty sure the security people can do whatever they're supposed to do regardless he has been accepted as citizen or not. Just out of curiosity, how many people that have applied have been denied citizenship? Is there even a reason why we have to "screen" them before we accept their applications? This would alleviate any work the current Citizen-Initiator could do that Ecclesia can't do by itself. We'd just have to list whatever constitutes an offense that impedes anyone to be a citizen, like multiple accounts, is there cases of this?
The only sad job would be Delegate, the game doesn't really give us much options regarding this person, but an Allama-like standard seems to be pretty awesome, a spokesperson, representative, and that deals with pesky WA votes.
