The main function of the JSF is situational awareness. The F22 doesn't even have a functional data link yet. JSF has all of it built in from the beginning. Everything you add to an airframe costs millions of dollars, and there's no point in doing it.
STOVL is an important part of the JSF program. The F22 isn't capable of doing STOVL or carrier operations, you don't refit a non-CVN capable aircraft for carrier operations.
F-35's MADL wasn't added to F-22 because Air Force deemed it "not ready to use" and cited maturity problems with the whole stack.
A lot of JSF sensors are to patch over its horrible pilot situational awareness, mostly a legacy of the STOVL variant (which is responsible for most issues) and which exists only because USMC needs it to fight against Imperial Japanese Army in Guadalcanal. Few other purchases of F-35B happened because building a proper carrier would result in political shitstorm (Japan) or because F-35B being supposed to let build carrier more cheaply and when its issues became known it was too late to refit the carrier with catapult (UK).
As for refitting a non-carrier aircraft to be a carrier aircaft - F-18 is the best known case, and its competitor was navalized F-16. As far as I know, there was carrier variant of F-22 in the works as well.
The JSF was designed around sensor fusion to give the pilot situational awareness like no other aircraft.
Stovl has been used by the USMC in every conflict since they got the Harrier. They flew off of highways in OIF. Japan hasn’t purchased the B model yet, they likely will. But the B model has doubled our carrier force by giving the ARG strike capability.
You do not “refit” a non naval aircraft for carrier duty. The f18 was designed as a carrier aircraft from the ground up, and there was never a carrier variant of an F22 except in some people’s fantasies.
You don't usually already produced units to "navalize", but making a derivative is the norm, and was the case for both.
F-22N was proposed but never went far.
As for JSF sensor fusion - the helmet itself comes form pretty bad visibility from the cockpit. Incorporating modern passive sensors was an obvious choice, though.
(I'm still waiting on reports of "sensor fusion finally works", given our local idiots in charge decided to jump on the Lockheed Welfare project)
And outside of F-35, everything talks Link-16 with possible tunnelling/subnetting, and MADL was considered "too immature" to start fitting on F-22 despite Congress "ordering" it.
The JSF's sensor fusion is not a result of "bad visibility". It's how the aircraft was designed.
F22 also does not talk Link 16, for obvious reasons.
Guide the pilot into a suitable position above the landing area. (with visual indicators, much like those for a bombing run) Once the plane is in the right spot, a computer finishes the job with full automation. The aircraft is stalled. The pods fire rockets. The aircraft is guided down and brought to a stop.
This retrofit would be particularly sensible for the F-15, which normally carries conformal fuel tanks. That would be a fine place to install the retrofit.
Sounds like a great thing for a scifi novel, but not useful to do something like that in real life.
The idea is not feasible.
Also your list of "carrier aircraft requirements" is incorrect, the JSF is a single engine aircraft, and landing gear is a major requirement of a carrier aircraft. The F22 is not a naval aircraft, was not designed to be, and never will be.
Doing that for fighter jets is actually much easier. The speeds are much slower and the distance is much lower.
It's absurd, as anyone who spent 9+ years on CVNs would know...
