Decided to make Elsa a sister.

Comes with 2 files: on the exit of Vault 111 (so you can make your own edits), and Commonwealth (outside of Vault 111).

Update:

I'm adding follower replacers if you want Piper, Cait or Curie to look like Anna.

Installation:

Place any or both of the save files with your other saves. Default is My Documents/My Games/Fallout4/Saves

For the follower replacer just download the one you like with NMM or download manually and extract into Data folder.

-OR-

You can use the amazing Face Ripper to transfer Anna's face to your own save.
