This game was also called "Imperial Fiddlesticks" in a text called "Curiouser&Curiouser" (also by V.R.Parton).
Castling is not mentioned, but I should assume castling is still allowed, although the restriction of not moving into/out of/through check is ignored.
However I may suggest a further variant: You don't lose if you have more than one king. (For example, if you have only one pawn and no king, then promoting will cause you to use instantly, but if you have one pawn and one king, then if you promote, you won't lose until either one of your two kings is being captured.)
