It would be possible if someone could just figure out how four tildes are converted to a signature. Then you'd be able to use a bit of javascript to check whether you're on the MessageWall thread namespace (1201 I think), and make the four tildes convert to something different (rather than what's in Preferences).

Another remote possibility would be to use a conditional parser function to determine if you're on a thread and stick it in your Preferences. (You can google "mediawiki parser functions" if you're interested in reading about it)

I'll let you know if I figure out any feasible way to do either of those things.
