Certainly making it so that the Wuss only needs to be captured (if there are other kings on the board) would make it less weakening (wusses weaken chess armies by their very presence). One might be wise not to go after the wuss in such situations but to save it for last since it is relatively so easy to mate. I feared adding the Wuss under its usual conditions (Game ends when it is checkmated) would be overly weakening. For the time being, I'm on board with the idea of saying that supernumerary kings need only be captured.
I didn't read Nicholas Wolff's suggestion when I wrote the above phrases. I'm on board with his idea: Checkmated Kings should simply be removed from the board if other un-checkmated kings remain on the board. If two kings are checked simultaneously and both must flee, the defender should choose which to remove from the board and which to move from check. I'm assuming both kings aren't checkmated in which case they would both be removed from the board before the defender can move or the game is over if there aren't additional kings on the board.
