Don't know where you got those F-16XL numbers, but they are way of. Those numbers looks more like standard Blok 15 numbers.

The XL had a max T/O weight of 48000 and carried 80% more fuel internally, so closer to 13000 internal fuel.

Payload significantly larger than what you are listing.

Regarding fuel and max T/O weight and reange - I can't imagine a scenario in todays world where you wouldn't get tipped of by a tanker after T/O before going on with your business.
