pipe with different diameters (steady and sudden expansion)

I'm having difficulties meshing a pipe with varying diameters. You can find the geometry below. As you can see the pipe starts with a big diameter then gradually becomes smaller until it suddenly expands to a bigger diameter again (symmetry after this point). The idea was to use a hex mesh.
I created 2 body parts in design modeler, the first part is the big diameter including the cone (cone part) and the second part includes the 2 smaller diameters at the sudden expansion.
I started to generate a mesh for the 2 diameters at the sudden expansion, where I applied a multizone method and an inflation layer. The "cone body" was sliced in design modeler and its mesh (multizone method) was generated afterwards to fit with the existing mesh.
Due to the cone expansion the cells become larger and so does the inflation layer in the cone part.
My question is: how do i mesh the cone part? I'm not sure if my approach is correct or not. How would you mesh the entire geometry?
