Neptunia Weapon Models Mod/Mods

A little bit ago, I said in the shoutbox that Payday 2 needed more Nep. As in Neptunia. I said that someone should replace something like the r93 with Black Sister's gun, and they decided to give me this dropbox link, which if I'm not mistaken has all of the weapon models and textures from Hyperdimension Neptunia. Would someone be able to do anything with this, I.E custom models to replace weapons with, like I said with the R93?

There's an R93 in Payday? Last I checked the only Beretta Payday had was a 92FS.
