you may well be technically correct - however isn't the lesson that leaps out from JSF (and everthing else we've ever built/bought), that 'a little modification, nothing serious', soon becomes 'fcuking how much!'?
my cynicism is driven by the fact that when i was a kid, JSF was going to be a 60-80% parts commonality airframe, it would be more manouverable than an F-16, it was going to cost $60m apiece, and it was going to be in service in 2006 or so.
this is a platform that burns £50 notes to such an extent that no one is looking at developing something as simple as an external fuel tank to hang off it because of the cost that seems to develop when anything, regardless of how simple a process it should be, goes near an F-35.
