ICANN would likely not grant such a tld due to similarity concerns with .us/.gov. You can do the same thing without a tld of course: <original domain>.pubmirror.com (or whatever you want to use) is just about as easy despite an extra dot. My personal fqdn is even shorter than ".usgov"! The hard part is recreating/mirroring all the stuff.
