Answer 1

If you are condisering making the original fly farther, the quickest way would be to place a supplementary fuel tank in the tail.

This affects the centre of gravity on take-off, but other loading measures can be taken to counter-balance it, and it is temporary, as imbalance disappears as the fuel is used.

Airbus already knows how to do this as it was done on some A-310 models.
