hey, does anyone have any exprience making/hacking together skins?

i got this awesome glock skin, but there's a few problems with it, and i was wondering if anyone here would be willing to make a few edits for me. first, the model's a bit big for a glock, but that's not a big issue. the skin uses valve's default glock animation, but i'd rather it use the animation from my previous glock skin. i switched because that one didn't have a world model or reload sound, but i loved the anims. so if i were to give you the two skins, would you be able to decompile them and make the animation change?

this is the skin i have now, but want a different anim.
