What you're suggesting requires a ton of money for some questionable benefits. Now electronics is a big part of an aircraft's cost, and doing what you're suggesting would mean ripping out pretty much all the control systems in those planes, probably refurbishing the airframe, replacing the old electronics with new ones, integrating the new electronics, etc.
Doing all of them in the required number requires a lot of money, not to mention after doing all those things all you get is a just another drone, one that's a pain to make and even more troublesome to integrate into your supply chain and maintain. IMO absolutely not worth the trouble.
From your proposal, I think only the repurposement of highway into runway can be looked into. The rest are just a waste of money.
... if legit this image looks to be the first confirmed image of a PLAAF CH-5 with the 51611 serial number. This would indicate an ECT subordinated Brigade.
