New Weapons for H&D2

I've been thinking if there is somebody who could make new ww2 weapons example: Welrod for H&D2, or at least edit the current 3D model into a Welrod model and release it as a mod.
We could really add some weapons that developers forgot or did not have time to make.
Some examples of this weapons:
WELROD

FG 42

Walther P38

MAB 38

M3 Grease Gun

AND MANY MANY MORE!

If you just change the 3d model but not the weapon characteristics I don't see a point in just adding "fake" weapons. That said, I like functional mods and not so much eye candy unless it simply enhances the game itself like high resolution graphics or sound. Sometimes when I see the mods people use and their fantasy color scheme it makes me cringe.

No no, not only change 3D object of weapon and voila .
Things like recoil need to be changed too, good point NL. Like the FG 42 recoil would be very hilarious example check Call of Duty.
I am not really into digging the H&D2 files but if somebody does please send me 3d object of H&D2 weapon
i'll see what i can do in Adobe Photoshop.

Thank you very much Stern! I think 4ds can be imported.
