Can I change my Crew Members Names and Faces?

[McHub532]

I had a little fun going into my:
C:
..>Program Files (x86)
....>Ubisoft
......>Silent Hunter Wolves of the Pacific
........>Data
..........>CaptainPicture

And found picture.tga

Neat... so I did a little cut paste, resizing and converted a jpg to tga and whammo.. the picture on my desk in the office is whatever I want it to be.

This of course made me feel brave, so I started looking around in other subdirectories for neat little bits that aren't too dangerous to mess with.

>My Name Here
..>Documents
....>SH4
......>data
........>cfg
..........>UserPlayerContext

I found a file named: CrewMembersNames

Now... can I edit this file just putting in the names of my friends and have it work and not mess up the game? It can't be that easy can it?

Part 2:

Is there some way I can get little pictures of my IRL friends (.tga format if needed) to replace all the little faces of my crew?
