Spandex,
If you determine your required touch-down point, e.g abeam a certain taxiway where you know runway remaining, then there is nothing wrong with displacing your touchdown point.
DXB in a bizjet comes to mind - when your first allowable turn-off is 2800m from the threshold and they're working with 3-4 miles spacing, it takes no genius to work out that if you land in the TZD, the next guy goes around, indeed, ATC request crews to plan accordingly.
Obviously, if you can't identify your new touch-down point, SOP prohibits it or there is good reason why you would not do it, then you're back to plan A - and if you sail past your new touch-down point, you throw it away and go around - just as you would had you sailed past the TDZ...
