Make The Cushions Be Able to Pick Up Mobs

I think it would be cool if the new cushions could pick up mobs similar to the boat and minecarts. I think this would be cool so you could have mobs sitting without using minecarts and I think it could be useful in a technical way since it's something you can place that can be placed like a block. I also think there should be a way to boot things off the cushion like activator rails for minecarts. I don't know how you would implement this, but maybe powering it but I'm sure there's better options.
