I'm not against the idea, but I don't know if FuseCrap supports automatic title except based on post count (I could be wrong). The mods would have to manually issue Lifer status. Lifer status (despite the name) is based more on activity (post count) right now than quality or time spent here, but if vB ever gets implemented, I say we base it on a ratio of time since registration to post count, such that neffers don't get lifer status too quickly, and people who post less frequently but over a longer period of time get it faster.
I don't know if that will confuse the crap out of new members, though, or if it would be easy enough to implement.
