I'm not even going to get into the concept of static models for weapons and the fact that it would take a ridiculous amount of work to do this, not to mention the data load of the game multiplying it's item database by at least triple in order to accommodate what is a virtually inane feature. We aren't even getting expanded inventories until the next expansion due to whatever data limitations, and your suggestion is to triple server load with a virtually useless glamour feature. I don't think that it's feasibly functional, and while I appreciate you wanting to express yourself creatively, I don't see a feature like this being implemented.
