An idea of mine from a few years back. It's actually an amphibious assault ship, hence the well deck. French aircraft carrier Charles de Gaulle has similar characteristics with...America class.
PS - the layout of the catapults is not final.

I see that Naval Group (formely known as DCNS) has a trimaran concept called "Ocean Avenger" (looks like an evolved XWIND 4000), getting closer to my idea. But from 4000t to over 40 000 is still a long way...
