If the lifts are big enough on CVF, they could take a fully spread chinook or Merlin as they are almost the same length and rotor diameter. But less chinook needed for lift = less cabs in the hangar below. At least the chinook (x4)could do a company lift in a oner. I don't see a wheezing Marinised Merlin (or six) being able to achieve the same capability.
LPH can't take either below without ripping blades or pitot tubes off.
