Hi,
as others mentioned already, this would not only confuse the clients and
possibly the users, but also create a bunch of unecessary beacons.
Not really sure what you;re trying to accomplish overall, but I believe if
you do what Nico recommended to try to keep the signal "in" (not allowing
people w/ lower rates/ possibly and hopefully clients far away without
high-gain antennas and stuff, to associate to the network) and use
encryption, even vpn on top of the layer 2 encryption.

my rusty 2 cents
