Which again begs the question - why two? Wouldn't the money for the second be better spent buying more approprately sized 'amphibious commando' vessels (and perhaps even more than one of them!).
I wonder how tight the contract is for HMS Prince of Wales. Construction has only begun on the QE and I think the orders for equipment has only been for that one. Besides, it does seem a bit odd to have a great big 60,000 tonne vessel dedicated only as an amphibious commando ship. Surely, if The Times' article is true and that is the proposal then it could revert to aircraft carrier when QE is in refit or if other circumstances required it to do so.
