yeah that would be possible but if you have enough harddisk space left just make 4 LFS gamefolders because there are more folders then only the dds folder (PIC,SND,OGG)
example:
C:\LFS
C:\LFSSnow
C:\LFSDesert
C:\LFSNight
make 4 shortcuts in your startmenu or desktop with each a different LFS name
that way you dont have to mess with files and folders..

Put the .dds files in the DDS folder. I havent downloaded this mod yet, so i dont know where to put things. Theirs most likely a readme explaining where to put stuff..
Though it is possible to edit the exe, it's better not to do this. I tried to search for temperatures, but couldn't find that. "20" is too common value in the memory. I also wanted to find the air density, because on Mars it is 100 times lower.
