You could try some riser plates, but it will put your center of gravity higher up. There are a lot of bindings with adjustable toe/heel ramps so that you can cant your protruding heel and toes upwards. A forward stance is easy to get higher binding angles so that your feet don't stick out too much. And if you're taller you can obviously widen your stance, rule of thumb 1" wider than the width of your shoulders. They're hard to find, but some boards come in mid-wide.
