Z horses and giants in sieges

Sieges are pretty boring. They are just tons of mobs spawning in a village randomly. But I think it could have more of a use, and for people to want to wait until one happens, by using 2 unused mobs, the zombie horse, and the giant. The giant could have more of an ai than it already does, and there be only one giant in the siege, and it can destroy weak blocks by walking on them, and it’s attack could be stepping on villagers and the player. the horses could be saddled with mobs riding them, and the mobs could have a small Chance to have bows and crossbows, and all other Z types could be in the siege, except the piglins. Also it would be nice if you could port the siege to bedrock edition, because it is currently unused.
