Change skin Type/Quality

Hi people, i know to get GO Skins its impossible. But its possible to change the weapon type/quality?
For example i got an M4A4 Tornado skin with "Field-Test" type, i want to change it for "Factory New" type because any weapon with "Minimal Wear" or less its kinda ugly.

PS: Sorry for my bad english.

The thing about that is skins aren't something on your computer. They're stored in the steam cloud and altering the steam cloud is, for now, not possible. (almost sure)

bet it´s a keylog or sth.
