Dr. Mundo: Should he embrace the agony?

I was thinking for a new backstory for Dr. Mundo, maybe helping the process for his VGU (we NEED it next year, Riot!). The new iteration of his lore makes it a complete mysterium where he got his powers, while before he was the Dr. Jekyll and Mr. Hyde trope by mixing a potion to become the perfect soldier.

Both versions don't really hit the mark for me, but I had an idea for a new origin of his regenerative powers and his obsession with pain. The cause I had in mind would be Evelynn.

It would basically be an alternative version for Dr. Jekyll and Mr. Hyde, he became like that by his own experiments (so yeah, he used to be a doctor for real again), but the core of his experiments was a sample from Evelynn that he got when he encountered her in the depths of Zaun (and he survived it!). It just makes so much sense for me. Both have skin color that goes in the same direction, both are tying together pleasure and pain, Evelynn even has a passive that gives her high regeneration in her demon shroud.

I think a scientist who experimented with demonic powers in Zaun could be interesting, but his motivation is not entirely scientific. Dr. Mundo always has been a masochist and this encounter with that beautiful creature ripping his flesh from the bones fascinated him. He is experimenting to become more enduring for her gifts.
