[Mod Request] Swaping St. George's sword apperance with Herod's Swords appearance

As the title of the post suggests, I’d like to rquest someone help me in swapping the apperances of the St. George sword with that of Herod’s sword. Idealy, I’d like to learn how to do it my self, but if someone has already done this, or has the ability to do so themselves, then if they could upload it here that would be fantastic!

Cheers,
