i don't think it would be possible, as browser companies would have to incorporate these new domain names into their software. Even the new .shop .chat and the other new.net domain names don't work on some machines still, the only way they worked was installing an actual program to make them work, or waiting for the new release of internet explorer to come out or something.
I think the main reason they don't work is because browsers are only designed to accept the proper addresses, i think its set so if you type it in wrong it comes up with an error saying you've typed it in wrong. So domain names such as www.bbc
would come up with an error, and that would be very hard to change i'm sure.
