What is the purpose of the the re-raise? You seem to be saying it's risky to be playing against what might not be a big hand. E.g. he's playing 65 suited and the flop could come 5-5-T. So the re-raise would be to get him to fold pre-flop. If you're successful, great, you've won $1.50. Even if he calls, he knows you've got a premium hand and he's not putting any more money in unless he hits the flop for 2 pair+ or a massive draw (in which case you're in big trouble anyway).
The reasons I normally re-raise with KK are to isolate and for value. Here you're at a 6-seater table and two of those players have already folded, so isolation is less important.
Regarding value, as already mentioned, this guy is less likely to get his chips in if you're telling him you have a monster hand. You have to play the players. A maniac is going to throw their chips whenever someone doesn't appear to be very strong.
I'm not saying that re-raising is wrong here is general, but against this sort of player just calling when they've already raised can be more profitable.
