Your looking at it wrong. You don't expand a restriction because it's similar to other restrictions. You would expand a restriction if the causes for the restriction are the same.
So if people start robbing banks in Burkas then you deal with the issue but you don't ban a burka because people rob banks in Balaclavas.
As an aside can you really not have your face obscured in a bank? Is that a real law, or just a businesses policy.
