A restriction of one Pawn to a file, even when moving ringwise, might prove interesting. The Pawns would develop as in the original game, but after one is captured its neighbors would be able to shift to its file.
And with their ringwise move, the Pawns now are able to defend one another. So a form of Pawn structure might be developed. This is probably essential with the increased power of the other pieces in this game.
