Hi andras, also another problem that you will kind of run into is that trying to make a blend that covers a rather large distance and between shapes that have a tighter bend in them will tend to make bunching.

That's because blending tries to keep its surface to be perpendicular to the edges.

When something is forced to be perpendicular, and also travel a fair distance, and also go through a tight enough curve all at the same time, it tends to create a kind of "bunching" like this:



That will probably create some surface artifacts like weird little wiggles in your result when there is not quite enough space for the blend to easily fit.
