batch - Combine two sets of folders into new structure

I have two sets of folders, which are two versions of the same data with identical subfolders (200+). I need to combine the sets using a batch into a slightly new structure. For instance:

setA\folder1\A_files  
    \folder2\A_files  
    \folder3\A_files 

setB\folder1\B_files  
    \folder2\B_files  

    \folder3\B_files  

I need to setup setA like so:

setA\folder1\A_files_folder\A_files  
            \B_files_folder\B_files  
            \A_files  
    \folder2\A_files_folder\A_files  

            \B_files_folder\B_files  
            \A_files  
    \folder3\A_files_folder\A_files  
            \B_files_folder\B_files  
            \A_files  

Basically, setA gets two new folders, one for a copy of A_files and one to move B_files into. In the end, nothing is removed from setA and the setB folder will be deleted.

Simple, but hard to explain.

Thanks for your help!
