Do you guys think I should also make cultists endless so they can't be taken as monster trophies and held to stop them from coming back?
Yes. Although it's probably not a big deal one way or the other (since the doom track is short).
Also, just remember, if you want Cultists to go somewhere other than the Outskirts, you need to specify where (since there is no rule for that kind of situation).
