The perfect Java cycle

HR Version, 1.Rb7!
(= 9+4 )
The point of the version is of course to have the Java cycle without any capture, be it White or Black. Had to pay with a lousy key. (Not that the original had a brilliant one... :P) And nobody else had that idea before me in the last 10 years?

Probably someone thought of it but did not want a flight taking key.

I think Kofman has done this in the 60s.

He did (and it's a great problem, 31791 YACPDB)...
but I concentrated on capture-free! And none of the
24 problems in the Albrecht collection (first by Segers,
BTW) apply. Thus I asked.

Impure but capture-free thematic variations?

(deleted - the stupid S guards the thematic field AGAIN,
and I thought I avoided that...)
