Conquest of the Horde

I was just considering the amusement when Horde and Alliance DK roleplay in /say when i thought of a possibility which may (must most likey, not) be possible

There are some items which have a default + skill to them, like +5 fishing, +5 skinning etc. Is it perhaps possible to inbibe an item with +# language? Like +300 Common. I know it's a long stretch (since blizz automatically disabled Common for Forsaken).

*prepares to get shot down*

They're hard-coded to never speak the opposite language as far as I've known. You just need to talk in /me.

Then perhaps create a language everyone can understand and hardcode it in as default?
