best way for loft sections between two changing size faces in different parts

Hello,
I have somewhat of a niche usage here but curious of how other would tackle this:
I have this geometry:
here one can see, that the surface blue, has a sketch where its projection is divided in several sub domains. on the other side, we have the grey surface.
if I want to create a solid that is the loft of the two surfaces, i would extrude up to surface the complete sketch (using the blue surface) and then the straight face that would be over the sketch plane, use loft with the grey surface. this creates a single solid and is a common approach of CAD. but i would like to do, is keep the solid divided, what i mean, for example, here get at the end 17 different solids which when fused together would generate the previous solid (that i described how to create, ie., extrude+loft).
what would be the correct way to approach this?
right now, I am creating a second sketch over the grey surface similar to the one already created but 'scaled down', extrude each element to the two surfaces, get the new sub faces created over the surfaces and then loft one by one.
this workflow is tedious but it does the job (keep in mind that in my example i just gave, the surface are scaled down in one direction and radially, but i am searching for a better workflow for a general two surfaces, of different sizes)
one would get this at the end:

have you considered creating the solid with a simple loft, then some solid & surface extrudes to intersect/split the loft?
Hello, thanks, I thought about creating the loft and then cutting it, but not sure how i would go in a clean way
it's hard to tell from your image but is this spherical or cylindrical? or neither? if possible can you share a link to what you have so far?
in the case of the image, it is a cylindrical faces, but I am looking for a general method, where one of the faces could be rather different to the other one. something like 'loft separately' or something in that vein.
In the case of cylindrical… make a surface, a sketch, wrap the sketch on the surface with the split option, then thicken the pieces of the surface.
havent used the wrap, nice to know, this can work for specific cases where there are the same height, but not for different faces, in any case thanks!
