since the domination mission file already uses mods, the option is there to add a small mod to reconfigure/retexture weapons.
only looking at around 3mb per texture probably less.
for example replacing the lesser used textures for the mk-1 (woodland/multicam) with new textures such as this one (quick test).
if it's something you want to see leave a comment, easy enough to do as long as @Mitch (IFRIT) approves.
