V22 has a breadth (rotors turning) of over 25m. Add landing scatter of at least three metres per side and you get a minimum safe landing width of over 30m.
Accommodating that operationally on an LHD (flightdeck wdith 33m or so, less the 8m width of the island) is going to be "interesting". Yes, you can overhang the port side, but that may well incur differential lift issues. Either way there are going to be no parking signs all over the Ouija Board - not smart for an aircraft carrying ship.
QE is a slightly different kettle of fish with double the flightdeck beam, but it's still a huge swathe of real estate to surrender. Any concerns about brake failures with F35 and SRVL are going to be dwarfed by those where you've got two 11m rotors, spinning at several hundred rpm coming down the deck at you. Very definitely not for the faint-hearted.....
