Replying to Adjusting Bindings Rather Than Redrilling?

Holla,

So I have been pondering this question for a while now, If I am looking in to getting some skis with Look PX 12's already mounted on the ski for a 316mm BSL and my current BSL is 305mm should I be able to adjust the binding the 1 cm inwards and avoid remounting the skis again?

I know this is possible with other bindings, but I have no experience with the PX 12's so some help would be appreciated!
