Interesting for sure, but not happening anytime soon...
Production ceased a LONG time ago, and its doubtful the US could have resurrected it even if it wanted to/had the money. It's a tiny, silver bullet force for USAF and has sensitive tech that's all too easily compromised. See the Lavi now flying as the J-10. Besides, Israel already has the qualitative edge, a 5 plus year head start with the F-35 (2016, first deliveries) and the UAE won't be getting there's for some time - likely years.
Unless USAF has an equal or greater number of NGAD/PCA aircraft flying we don't know about, no American F-22's will be sold to them (or anyone). The F-35 should be more than adequate especially given the "unique" modifications we allowed them to make to the airframe. Doubly so, if they get the AIM-260 in the near future.. which I bet is a distinct possibility.
Appreciate you making this post though, it's an interesting development.
