What if Battering Rams were available in Feudal, and Capped Ram in Castle?

Stone walls are effectively impregnable in Feudal, even with that change that halves their hp until Castle Age.

Battering Rams really struggle to kill castles in Castle Age, it feels like if you want to kill a castle you HAVE to go to Imperial Age - assuming the enemy isn't afk letting you do what you like with rams and petards.

It's a good part of the game, with its mediaeval setting, for stone defenses to be SO durable; but isn't it a bit over the top at present? What if there was a viable option to kill walls and castles an age earlier than currently?

(N.B: I'd suggest Siege Workshop becoming available after Blacksmith, but obviously no scorps/mangs until Castle)
