Nostalrius Begins - Quality wow vanilla realm (1.12)

Is there any possibility to change nickname of character?
My friend have me a hunter, cause i spent many months on playing this class on TBC and he though i might be interested in playing hunt on vanilla.
So i just wanna swap nicks between characters i own, because i'd like to use nick of my first char I play in WoW ever.

Can it be made somehow?

PS. Sorry for my terrible english. It's not my native language and i wasn't use it since 2011 :/

It cant and dont tell anybody what character you got gifted. Gifting is against the ToU and can get your gifted account banned.
