Fillet or Loft to solve a Ramp

I would like to create a curved transition between the inclined ramp and the landing (which is also curved), smoothing the slope.

The Building (for Context):

I tried using “Fillet,” but the resulting curve turned out more cylindrical than conical: it ended up parallel to only one of the faces.

The Ramps (already modeled):

My goal is for the curvature to align simultaneously with both faces, in a somewhat conical fashion.

The detail (I am looking for):

Is what I’m looking for actually possible…? Should I try using “Loft”…? But how do I draw the guide curves correctly…?

Like this?

Hey.! Look great. Thank you. What have you did…?

I forgot to share my model file…

Basic technique. I just used two profiles and extruded them with Intersect.

Ah… Creative. I will try.

(buy the way… Loft doesn’t work in this case, right..?)

Loft would work too, but it would be much harder.
