Possible to make Rail Revolve work with Two Profiles?

Wondering if it's possible to make Rail Revolve work with two profiles.

Much like 2 different profiles in a Sweep smoothly transition from one to another.

I have a situation where my curved profile has a bump where it meets the 3D rail curve at 0 degrees, but I want the surface to transition to a smaller bump at the opposite end, 180 degrees.

I can accomplish this with Network followed by a Sweep around the perimeter using 2 different sized profile circles.

But for the future, Rail Revolve is so easy to use and modify by just tweaking a profile.
