I don't really see the point on re skinning again .. people kind off got over that. If you publish it public you will get it patched .. if you send it to a few people they will spread it eventually just like cfrez guys xD. I did something close to your work but instead of hacking the game and changing the textures I am converting the LTB models to readable models (I did a little showcase thread on the mod section if u want to take a peek) .. i want to try and re build crossfire in unity but with a server sided server so I can eliminate cheaters.
Anyways my point being: if you want to make some money of it sell it.. even if it spreads all over the internet you will get some income of your work... if you are generous and don(t want any reward just publish it to public.
I my self never enjoyed skins that much .. the reason being if you replace the knife for an axe the animation speed will be all wonky.. (it happens to other weapons but this was a clear example) it just fells weird for me. Weapon hacks ,when they were possible, were the best
