Well, if they're only used for initial training, then ya. But worth pointing out that right now, there are ~13 active duty USAF F16 squadrons, something like 17 ANG squadrons, and ~5 training squadrons. That's roughly 6:1. The USAF was planning (who knows...) to get something like 1500+ F-35s. Even at 12 active airframes per training airframe, you'd still be able to absorb 108 airframes. If these airframes can be made into sufficiently good trainer airframes, then it could be okay. That's a big if though, looks like Block 2B have lower G limits than the Block 3s - don't know if that's a real structural thing, or just software qualification stuff.
