Rail height has nothing to do with it. It's the turnouts where the issues lie. When I was with the CASG modular group, we used AM's code 148 rail and could run scale wheeled stuff on the outside loop because it had no trunouts. The inside loop had one turnout and was limited to HiRail or Flyer.
There is a mod for Fox Valley's HiRail turnouts I've attached below from the S Scale Facebook site that will allow both Scale and Hirail operation.
I haven't tried it, but reports are the mod works well.
I have the instructions and photos in a Word document that I am happy to email to anyone who wants it. I also have videos of some of my tests. The problem at present though is that FVM is sold out of hi-rail turnouts and the new run that was due in November have still not arrived and it is not known when they will.
