The hole pattern for the AT bindings are different to the regular alpine bindings as can be seen for the jester and duke templates here

You could re-use the front two holes for your squires and just mount binding freedom inserts in the other AT pattern holes but i think you would have clashes with other holes. I dont have the jig or the skis to physically check, you would need to print off the template and see for yourself if you would have about 10mm+ clearance on the new drilled holes. you then either have to be confident mounting the inserts yourself or find somebody willing to do it for you.
