it looks for me like a non-sense to install both cat and sky jump ?!
the interest of the VSTOL or STOBAR is them no need cat, and then, they can go almost anywhere flat.
but if you have allready a carrier fitted with Catapult for the E 2-C, why for God sake not use them for the fighter/bomber ??
it can be F35, F18, or Rafales
evens the F35B is cancel or are to expensives, you still have the Rafales or F18 way
