This is a pipe dream as of now.
Any alterations to existing F-22 would cost dearly.
Not to mention only fixed amount of airframes are built. Restarting production is nearly impossible as that would mean the death of F-35. Not to mention retooling and re-creating the design charts (the old modules and charts are usually destroyed after completion of production for safety reasons).
@BON PLAN we have seen propaganda from LM that it is the best(better than F-22) kind of bullshit and from LM counterparts stating F-35 is a turkey, a leamon, "can't run, can't hide, can't kill" kinda stuff. So let's not get ahead of ourselves in celebration based on simple propaganda article no better than tissue paper, in fact tissues have better uses than that article.
Purchase of aircraft or any defense equipment in still in the hands of Senate. Though US armed forces makes suggestions, final word is in the hands of Senate.
F-35 parts are being manufactured in 45 states, there is no way that Senate and governors are going to loose jobs based on ill performance of few hundred fighter jets, they basically don't care. Not to mention LM would be stuffing their deep pockets till money starts to overflow.
We all know how things work in US arms purchase....no matter what propaganda says F-35 is coming and in large numbers. Even if the disaster of F-35 being turkey comes out like "Growler debacle" or " M247 Sergeant York" there is no backup plan for another stealth aircraft.
Last but not least, I hope you know of Trump bashing EU countries for not doing enough for NATO military. During such tough times, how many NATO or EU countries are going to switch from purchasing F-35 to other aircraft and face the wrath of US or rather Trump. One last thing there is no escape for EU(except for France, maybe Germany) to buy F-35s. Not till 2050, even then there is doubt.
