Jack's Grandma

So we know that Jack hired some Bandits to go kill his Grandmother. What we don't know is that she was not home when they arrived. All that blood and stuff was from the skag she had just skinned with her buzz axe. I say Jacks Grandma would be an awesome dlc character to play as equipped with her trusty buzz axe.
How hilarious would it be to play as a Baddass old granny woopin some hyperion butt?
