Custom models folders

[Knusper.]

ah, ok.

Is it possible, If I and all ones who play the story replace the model folder with my custom latern, too?
Then you will use my latern in the original game, too, but thats not that bad, you can make backups.
And the story will only be played by my best friends.

Is that possible?

(sorry, maybe i could try out that all, but i think like this its faster and safety )

edit:
thx for double answer^^
