White king seems unneeded and it even destroys the quality of final positions. It is possible to do implement the idea without it (using a white royal pawn with a promotion key).

It is even possible to double the idea with some Royal dynasty.

Some more changes would be necessary to deal with the defence 1…h5 if the wK is absent. Perhaps bP>h7 and then everything turned 180 degrees (rZa1, Pa2), with a key that puts the wS within reach of a2?

No, on anchor ring the knight always has two ways to attack any square, if at all possible. So, only promotion key will work.

With key: 1.h8=S!
