Based on personal experience any open frog turnout that will work with scale and high rail wheels is unforgiving of incorrectly gauged high rail wheels. There might be a customer satisfaction issue if a commercial product were offered with a combination design.
Here is a picture of some of my turnouts during fabrication. the spacing looks wide in the picture but the guard and wing rail gaps barely pass a Gilbert or Lionel high rail wheel. Slightly off gauge they will jump up and usually derail.
