Replying to Making snowboard skis

so i watched head for the hills recently for the like the tenth time and i am really interested in making some fat buttery skis out of snowboards like the redneck rippers. i would mount alpine binders on em but i have a couple of questions. first has anyone done this? secondly how hard is it gonna be to find long snowboards in the 165-170 range for cheap? thirdly my friend mounts skis and he was wondering how hard it would be to mount bindings on something so thin. and finally if i dont have edges but just the wood/ptex sidewall since i would cut each ski out of the middle would these be impossible on groomed runs. the skis would be primarily for backyard/snowdays not really sure if i would take em to a resort. but anyways i think this would be wicked fun to make and ride. I would make them lizzie type dimensions if that helps any inspiration or help gets +k
