Dirk Borst made a Queen Schnoebelen with transmuting kings in Nunspeet a 
few years ago. It looked something like this:

rs3qsr/ppp3pp/3p1p2/8/k7/Pb6/1PPPP1PP/RSBQKBSR
SPG 6.0 Transmuting kings

And the first King Schnoebelen is, as far as I know one I made in 
Nunspeet, in, I think, 2002.

rnb4q/1p1pp2p/p1p2k2/3B1p2/2PPn3/4P3/PP4PP/RNbQK1NR
SPG 10.0, Extinction chess
