user26472: Relevant similar question:
Why can't a piece (that isn't a pawn) capture en passant?
Question:
When the game of chess evolved differently in various regions, was there any case in which the addition of the pawn's double move was accompanied by a variation of the en passant capture rule that enabled any piece to capture the pawn in the square it "skipped" over rather than restricting that capture only to opposing pawns?
(Not to be confused with the similar but orthogonal question, Is there a variant in which any piece can be taken 'en passant'?)

user4418: No. Such a thing makes no sense and so hasn't been done in regular chess.
Pawns can only move forwards, either straight ahead or diagonally forwards. Hence the need for an en passant rule when the rules were changed to allow pawns to move two squares on their first move. All the other pieces can move and capture backwards. Hence a pawn moving two squares in one turn does not escape the possibility of capture by another piece so such a move would have no rationale.
