But you could always add a restrictive rule, for example that the enemy pawn can stymie the cannon-rook compound so that it can only reach the square immediately behind the enemy pawn. Cannons are sometimes problematic in that they can cause devastation in a Western piece context, but if one introduces restrictive rules they can blend in. I have used exactly the above restrictive rule for my Basilisk cannon:
