Character Concept( for the UA armoror subclass) Big Sister

I just got a cool idea for the Armoror subclass in my campaign. If you are familiar with the Big Sister armor from Bioshock 2 

Armorer power armor is defined as "form-fitting"

The thunder gauntlets can be the syringe weapon thing they have 

The bonus action that gives temp hp is the blood in the syringe from the enemies after being struck by the syringe weapon

Do you think its a cool character concept? 

Tell me what you think!

Honestly, that's pretty perfect. I feel like a bioshock aesthetic fits artificer very well.

You could also mimic Big Daddy and play a Goliath armorer with a drill arm. Another player could then be a tiny gnome warlock that rides on his shoulder.

The tiny gnome is a perfect addition!
