Fascinating. Impressive. But you are not a Jedi Yet!
First you make skis have a super sidecut so they are all squirrelly, and then you sell runners to put on the bottom to counter that.
I really like the idea of having two sidecuts, one for long cruizer turns and one for short turns. I hypothesize that it will work too, provided that you don't try and make any serious LR turns. You can use the side cut radius when it's up on a big edge angle, and the runner's side cut with low angles. THE TWO PROBLEMS are that the runners do not provide enough edge for serious high-g LR turns, and you would be at a steep angle for high speed LR turns and then the side cut radius would kick in. In fact for me these skis would be downright dangerous.
