One thing you can do is use riser plates, which are usually associated with having too big of boot and having to deal with toe/heel drag. But elevating your boot/binding also changes the angle for edge leverage....so if you got a small foot/boot comparative to waist width of the board you can easily gain some advantage. The cons is added weight to your set up, the pros (or cons) is that your edge control will be tighter/more responsive....however if mastered you will have excellent edge control.
I made these 20mm risers years ago for my daughter, iirc when she was 9 or 10yrs old 90lbs, and maybe 4'10" riding an old stiffy FR Option Bella 148...a way huge board for her size but she learned to shred on that thing and became known to be one of the smooothest and fastest groms on the hill. Now she mostly skis 174 twin fattys with 122 underfoot cause she can go faster but she still ocassionally ride a 144, 148 or 155 now being 120 lbs and 5'3"
