Clip everything behind a compound path

Hello!

I have two compound paths and I want to mask the area of the one on top. Below is an example, where the figure on the left is what I have initially and the figure on the right is the result I am looking for.

The two parts of the image are always the head and the body. I want to place the head on top of the body so that parts such as the hair cover the body. 

A clipping mask does not do the trick, it simply results in the portions of where the two overlap. I have also attempted all sorts of path finder utilities like difference, merge, minus front, etc. None give the desired outcome.

One way that I can solve this problem which is an approach that I do not want to take, is to copy the head, fill it, then place that on top of the current head, select the body and use the "minus front tool". This deletes all the parts of the body that are underneath the head.

If there is a more efficient approach to this issue would be ideal because this is a process I have to go through on a daily basis and ideally I would like to try to automize it. 

Please find the illustrator file attached in case that you would like to attempt some approaches.
