It's interesting that both 'Mountbatten' and 'Windsor' are names that were made up a century ago.
If Charles wanted something altogether different, he could go with the "House of Edinburgh" The Houses of Normandy, Lancaster & York originated from the titles of the Dukes who founded them, and unless his father outlives his mother, Charles will be Duke of Edinburgh when he becomes King. That might complicate/confuse matters in view of the plan to making Edward Duke of Edinburgh once the title merges with the crown, though.....and there's the prospect of Scottish independence....
It feels to me somehow that Elizabeth will be associated more with her forebears than her descendants and that with the prospect of a Charles III-William V-George VII-son/daughter succession, a new House is in the making.
