Another problem is that Wilkosz may not be as effective constructively as the other permutations. For instance, it forces the responder to answer 2♠ with a moderate hand with four spades and two hearts and opener is supposed to pass without extra values.
(With AQxxx Kxxxx x xx opposite KJxx xx Kxxx AQx, it goes 2♦ 2♠, while 2♥ hearts and another or 2♠ Tutti-Frutti would make it easier for responder to relay and to end up into 4♠.)
On the other hand Wilkosz should do better with a maximum six-five, but these are probably too uncommon.
I am also not a fan of 2N as a single hand type. Maybe 2N as either both five-card minors or both five-card majors and a maximum, so that Wilkosz still doesn't deny both majors? Or (if you play WJ) 3♣ as minors and 2N as a club preempt or a very distributional hand with clubs, such as AJ874 __ A KQT9643, which forced Balicki to rebid 5♣ instead of 4♠ in the 1994 final after he had opened a could-be-a-very-strong-hand-with-spades 1♣?
