Force field beacon

I think it would be very cool if when you level your beacon up enough you have an option to make a point 32 by 32 force field around the beacon. You can level your beacon by adding more layers and rarer blocks like diamonds. Also if you have two dice field beacons next to each other they will combine into a larger force field. The force field will temporarily turn off if hit enough and will allow things through the force field while it recovers l. Also I think that you are able to adjust the size of the force field. Also you can have a way to only allow certain people or things inside like you friends, and maybe a remote thing to toggle it on and off from a distance.
