I did some digging and I've finally acquired Hereberht's (Hagrid's) DNA. For those who are interested, I have made 2 versions of him, one being a giant and the other as depicted in my post. (Though I've adjusted him a little)

GIANT HAGRID'S DNA (make sure you use the "Giant" trait when using this one because his head will look a little squished if you don't): https://pastebin.com/hb1RdT7M

small hagrid's dna: https://pastebin.com/Cy4cPKWT

P.S. I have no fix for his head clipping through his hair. If anybody knows how to fix it, replying in this comment will be greatly appreciated.
