Hey,
I could try with most male Npc voices, but i understand that you probably have quite a few people who can.
I have done a Khajiit voice before and tried Nord voices, but really I can do lots of voices and accents.
I have a incomplete khajiit mod with poor quality with audio ( i had an old mic) http://www.nexusmods.com/skyrim/mods/81670/?
If you need more i can send you something i record now.
