Mod making (Medieval 2)

So me and a mate have embarked on bringing Mount and Blade to Medieval 2.

Thus far, slow and steady.

However, I was reminded of my skull being used as a drinking object by some Sea Raiders and I was wondering. Are we allowed to use the Mount and Blade Warband sound files within our mod for Medieval 2?

I don't know if this is the correct forum to ask it but considering its the community forum I thought to post it here.

We'd rather ask permission before embedding the sound files so...Here we are.

Developers of Mount and Blade Warband, are we allowed to use your sound files to bring Mount and Blade to Medieval 2 Total War?

(PS. Moderators, if I've placed this thread in the wrong forum, would you be so kind as to place the thread in the right forum? Thank you)

Any news?

It's been standing still for a while. The other person that, initially, came up with the idea has had his laptop die on him and since then I haven't really had any contact with him. He lives in the States and I live across the pond so I can't really walk up to his house.

You can find the link to the mod and what's been showcased here; https://www.twcenter.net/forums/showthread.php?789871-WIP-Calradia-Total-War
