Smooth Intersection / Morph Data Control

Hi, I'm trying to Smooth a set of intersections: the connections between top surface and loft, between bottom surface and the loft, and also between the loft intersections.

The loft is from the division of each surface. The top surface is from flipping of a quarter "vault unit".

My problem is,

1. when I split the top surface, it didn't work on all "vault unit", just three of them. 

But I need to split all the surfaces on the top with curves on it, to join the them with the loft. And also the bottom surface, which has been lofted 4 times to connect each of the top surface, where I have the problem to split and join.

2. there are some weird lofting moments, seems they twisted 180 degrees. How I can make them all just direct simple loft?

3. this is a little different. I applied the baked component to a box morph. It works well. 

But is there a way that I can apply the unbaked component from grasshopper to the box morph, and get control of the items in it, saying,

1,3,5,7,9      loft shift type A

2,4,6,8,10    loft shift type B
