You could but this wouldn't solve the Enderman problem. You would have to use water and they would teleport. It would be better than the mob masher though. I installed ProjectV so I am mostly going to use the drops for emc (or whatever it is called) and the element table, if I actually end up making this. I haven't decided yet.
Is it possible to make it into a drop farm? Unless you need experience or specific drops, I don't see what you'd need all this for.
