Slow drones won't be able to engage an F-35 in A2A combat because that's primarily determined by energy state. A Cessna 172 can carry about 100lbs of weapons after taking fuel and pilot into consideration. A Stinger weighs about 30 lbs or so, so three could be carried. Range of the Stinger is about 5 miles, so still sounds plausible.

So your cloud of Cessnas could conceivably carry 60 Stingers. How will they detect a fighter flying at 30K? A 172 can only get to about 15K in perfect conditions. It flies at like 100mph compared to a Mach 2 F-35.

Again, short of being a suicide bomber trying to kill an F-35 on the ramp, this idea is ludicrous.

To add, the primary advantage that A2A missiles have over SAM systems is that the missiles dont have to fly up 10s of thousands of feet to hit their target. Modern "dogfighting" is about achieving optimal launch conditions(Altitude, speed, heading) for your missile against the target. So even if a Cessna could detect the F-35 and carry the most advanced A2A missiles it would still be thoroughly ineffective.

To create a drone capable of threatening an F-35 requires creating something very similarly capable in all ways but without the pilot. This may exist one day but it isn't going to come at a discount.
