Has anybody converted a Shimano HB-M756L XT Front to a 15mm thru axle?

The problem is that my bike fork has 15mm holes for thru axle but I have a new/nice set of QR wheels. I need to either convert the hub (change the bearings and etc) to a 15mm and use my original thru axle or use two spacers in the fork holes in order to fit them and use QR.
