Helicopter & VOTL carriers to bolster carrier fleets & other applications

I've seen people talk about aircraft carriers being "obsolete" which I disagree with, but I'd like to ask people what they think about having an additional carrier that would accompany the regualar aircraft carrier. The smaller carrier would carry helicopters and VOTL jets (F35B) and maybe Osprey's. I would think these would allow for the "auxillary" carrier to diverge from the main fleet for various missions, provide support for the vanguard or a strike force or hang back and protect the rear of the fleet - depending upon what is happening.

It could also be used to send air support to smaller conflict areas where there are no nearby army or air force bases, and this could be done while not diverting the carrier of the fleet from it's primary mission. I can think of all kinds of reasons these would be especially valuable like having some permanently in the Caribbean (off coast of Panama/Columbia/Venezuela) as well as maybe Puerto Rico (the two could also be used for issues anywhere in the Caribbean, central America and northern part of South America (to provide support of course).

These could find uses all over the place possibly in place of shutting down some bases, they could station some of these ships (along with escorts & tankers) near friendly countries who have hostile neighbors.

It seems that Japan thinks these area very good idea and they are planning on building a few more of them for their "national defense" (basically coast guard).

Are there any military, especially ex/current Navy men here that could offer some opinions on this?

The LHA/LHD, with the exception of the America and Tripoli, carry an MEU, along with the equipment to land them that can be launched from a well deck. America and Tripoli carry the MEU but lack the well deck. Their air compliment can vary widely.

The Wasp can go between 6 fixed wing aircraft, 4 helicopter gunships, 12 Osprey, 4 CH-53s, and 3-4 UH-1s, to 22 Osprey, to 20 fixed wing aircraft and 4 helicopters, depending on the mission.
