Unless there's some bizarre secret thing I don't know about, you should have no problem transferring rhe CMK stuff to the VIIC/41. They are the same kit, except for a few differences (bow, deck, tower).
Getting some advice form CMK interior folks will help tho. There are some at:

and folks all ovre the usual forums (here, Modelshipwrights, etc).
keep us posted on your progress!
