This works with educational related loadouts (e.g Albert einstein, Curie (if female mod installed) Stephen Hawking (ps. R.I.P Stephen...)) And works on the medic well as he's a doctor that experiments like it's the last he'll do. Maybe this could be a visual brainstorm of these characters.
Anyway, this would be great.
P.S: I didn't mention that ONE green shirt bald guy in the e.g bit because he isn't relevant and dosen't make breakthroughs besides arithmetic answers. Anyway, I bet someone will make a discussion about him on this item.
P.S.S: I chose those ones specifically because they were alive in TF2's time period. (Besides Curie. I didn't know that much so I threw her in on a lark)
