Swapping Heads in Dragon Age 2

I recently got into modding DA2. I started with model swapping through console commands and then I wanted to get into swapping heads, more precisely swapping Hawke's head with Meredith's. I tried renaming the head .mor file and placing it in the override folder, but whenever I start the game it changes. I managed to change the default head, and it worked in the prologue for the first 5 minutes, but after I got to the character creation screen, it reverted back to the normal heads. What am I doing wrong? How can I swap heads preferably add them as presets in the character creator. Thank you in advance.
