I just stumbled on a similar idea in Pritchard's Encyclopedia of Chess Variants. "Cataclysmo" by Bruce Trone, 1991. A piece's movements depends on the square it occupies. On even numbered ranks, a piece moves as a pawn. On odd numbered ranks, it moves as the standard piece that normally starts on that file (rooks on a and h, knights on b and g, etc.)
No mention of any special treatment for the king. Also no clarification of whether "even" and "odd" is in an absolute sense, or relative to the player but I think it must be relative -- that way, each piece moves from its initial position as it would in Chess. And nothing about castling, extended pawn move, or en passant.
