Ted, I don't personally know of any S-scale renditions of this, but it
certainly has been done by many people in other scales. I was involved
with the HO NEB&W layout at RPI when it was being planned in the early
70s and this was being done then.
As for standards, yes definitely keep the turnout itself level. Actual
practices vary from RR to RR, but the important consideration is to
keep your grades and vertical curvature within limits for your
particular operating equipment. You may find prototype standards
require far more space than you have available.
Hope this helps.
