Replying to Stretching Brakes for Powder Skis

Recently moved over to Rossland in BC for my first ski season, having skied in the Alps every year for 20 years. I've got myself a pair of 182cm 4FRNT Kye 120's for the sick days this season, and I am just buying bindings for them. The underfoot is 118cm, do people reckon it's alright to buy bindings with a 115mm brake and stretch them into place? Found a bargain for some Atomic ffg 14 bindings so hoping they could work with my set up. Thanks in advance!
