Replace MP5 for AK-74

[chezter65]

Does somebody know how to replace guns in Mw3?

I want to replace mp5 for ak-74. This gun can only be used in single player. But I want to use it in Multiplayer.
The options I used are

Search ak-74 and mp5 into iw06.iwd copy ak-74 to desktop and name it to mp5 and paste it in iw06. I did this also in iw10.iwd.
In game the mp5 is still mp5. Somebody knows more options?

It is not possible to use stuff from SP in MP in any way as far as i know.

Hmm ok, I think it must be possible. I think we must search it in texture edit. So I see the ak74 and but my enemy see a mp5

You are well aware that a gun in this game is a little more than just a texture? And that changing the texture won't change the reload animations, and whatever guns need in the IW engine?

Refer to skeletonmage's post, such a thing isn't possible.
