The problem with your argument is that you argue that F-35 is necessary to replace those aircraft. It's not. NATO already has several functional aircraft that do what F-35 does, and do it much better.
You argue that stealth isn't a big deal (in the parts of your post I just snipped), I'm not so sure. I'm also not sure that the F-35 compares as badly to the other options from our NATO friends. It seems to me that ALL your suggestions might fit the current need in the roles you suggest, with three critical flaws.
First, none of these are American made and that is a political problem first and foremost. No congressman in his right mind would suggest we scrap the F-35 in favor of buying our jets from someplace in Europe. So where they MIGHT be viable alternatives in features and performance you can bet it won't be funded to any large degree by congress and anybody at the pentagon that tries to suggest it will likely find themselves on the fast track to retirement. Nope, none of these will fly politically. Remember that the AV8B was a HUGE struggle because it was based on a UK design, and any program from Europe would suffer politically from the start for the same reasons.
Second, is commonality. The F-35's claim to fame really is Multipurpose, multi-role, multi-service and multi-country. Like it or not, realized or not, this is a huge selling point for the F-35 and one of the primary design goals. Having to maintain only one major design with slight variants will prove to be a HUGE gain in the long run. Now when you add a weapon to one variant of the F-35, the cost delta to get it on another is going to be pretty low. So when the Air Force buys a super duper air-air you cannot dodge it missile, the Marines and Navy get it too or when the Marines go buy some never hits the good and always hits the bad guys super smart bomb the Air Force can drop them too. Then there is the whole spare parts logistics thing... No, the F-35 has some definite advantages over randomly selected stuff.
Finally there is the stealth issue. Why carry some EW package when you can do without it? If they cannot see you some how, they cannot shoot you. Besides, the F-35 can do that role too, when necessary, then just flip the switch and disappear into the night when jamming isn't needed anymore. I personally think stealth is a big issue, even for close air support roles, where the aircraft is low and slow. Being stealthy will be an advantage in most situations and where the F-35 isn't 100% about stealth, the extent that it can just disappear will be an excellent advantage, if not a game changer in close air support.
So, Where I don't argue the capabilities of your suggestions, I just don't think they will fly for the US.
