Your welcome.
I have been frankenstiening figures for years, so for me it is simple. Once you do it a couple of times, you'll find it easier too. Just remember It's easier to use the body Cr2 Instead of the heads Cr2. You will have less joints to adjust if needed. It would only be the neck and head if you do need to adjust something. 

Side note. If the necks don't work or look quite right. Check the weld box on exporting too. You could just export both morphed necks out with weld and then import the new neck in before the main figures export also.

Many tricks, just practice and use what ever way works best for you.
