rebuild multiple surfaces into 1 surface

Hi guy :)

i need your help for a probably ( for u) easy question.

i'm modelling a organic form in gh+rhino and actually I have many surfaces in particolar two half sphere ( with some control points moved) and a loft between them. so three surfaces that are not enought fluid.

I need rebuild them in one surface for apply some smooth before work on it in grasshopper.

Any idea for a smart workflow?

thanks a lot ;)
