So this was my first model edit that I've done and I thought I should share something that I learned from this site. I've been a member of MMOwned for a while, but rarely checked back to these forums. Lately I've had a renewed interest in editing, and learned how to edit myself.
Human Female -> Prince Arthas
Tyrannical Beheader -> Frostmourne
If you don't use Tyrannical Beheader as your two handed weapon, then I found that using Glitchy's Model Swapper to edit your MH weapon to it will work, assuming of course that the Frostmourne edit is in your data foulder
