This seems like the most effective solution, but is it feasible to implement?
Two main things would be restricting this:
Is there a method of getting the karma/details of a user via a url? e.g. lesswrong.com/api/user/username/karma (Edit: it seems that reddit has this feature so it should be possible for LW)
Is it possible to hook a custom function into the log-in/new-user-validation of Mediawiki software?
Linking registration to LW accounts and requiring positive Karma balance could do the trick.
