Not 100% sure on this but...
create a new cs file for this...

using Terraria;
using Terraria.ID;
using Terraria.ModLoader;

namespace ModName.Fileblablabla
{
    public class ModifyDefaults : GlobalItem
    {
        public override void SetDefaults(Item item)
        {
            if(item.type == ItemID.Cactus)
            {
                item.ammo = AmmoID.Bullet;
                item.shoot = ModContent.ProjectileType<customCactusProjectile>();
            }
        }
    }
}

and then create your own custom cactus projectile and make the bow shoot that projectile.

Although now every weapon can shoot cactus i think.
Atleast its a start. Probably wont be able to help much more than this.
