I don't think that's what he's asking. He's asking when you could run into problems getting them remounted (obviously, done by a professional). Just look at the spacing of your holes.
The new holes need to be 1cm from existing holes. I can only speak for Salomon S900s (same pattern as current models I'm pretty sure) - the toe screws are about 3.5cm apart and the heel screws about 10.5cm, so you won't be able to have them remounted between 2.5 and 4.5cm or between 9.5 and 11.5cm forward. Anything else should be fine.
