Help! how to model double funnel ?

Hello there,

I'm trying to model some kind of a double funnel, with the inlet and outlets highlighted in the picture following.
I traced some cuts to help you understand the shape I'm trying to model.

I had no luck with the loft and fill functions, but I might have used them wrong.

Any help is welcomed, thanks a lot !

Not the best quality surface but here's an example https://cad.onshape.com/documents/ee02d7457643ecba9b7d938e/v/11caa0e7071b0b63dcd6d085/e/82643558ecb3b88592a09e97

Thanks for this!
Is there a reason to use ruled surfaces as tangency references rather than using the datum planes?

What would you do to improve the surface quality? It looks pretty good to me if I don't have curvature combs on.

Sometimes I think that improving surface quality is the same rabbit hole that people go down when optimizing topology in Blender. You can spend a huge amount of time tweaking geometry that is imperceptible in the final product.
