The only similarity I see with them is that they are both crazy people with guns and kind of sort of terrorists, Jhin being used as a weapon of terror by the cabal and Jinx just blowing everything up just to prove that she can.

- Is a psychopath. He meticulously plans every move he makes and he has quite the silver tongue.
- Is elegant in his words and movements.
- Is a serial killer.
- Finds beauty in nothing more than death. To him, there is nothing more beautiful than it.
- Has no romantic/sexual attraction to anyone. He gains pleasure from killing.
- Travels way to much to even interact with Jinx for more than a day or two.
- Is extremely relaxed and would find Jinx's energy infuriating.
- Would probably just kill her if given the chance.
- Seems to be in his late 30s-early 40s.
"I met Jinx in Zaun once.... Once."

- Is just insane, probably actually has some sort of mental disability that makes her so.
- Talks fast, moves fast.
- Blows shit up for a living. Deaths are on 'accident'.
- Explosions?
- No comment.
- Not sure if she travels a lot but she sure as hell isn't getting on a boat.
- Way to energetic. Gotta shoot gotta shoot gotta shoot.
- Would do something to annoy Jhin and end up dead with her chest twisted into the shape of a lotus blossom.
- Seems to be in late teens-early 20s.
"He thinks I'm dead. Hint; I'm not!"
Long story short I don't see it. There is the whole Joker/Harley Quinn thing, but honestly Jhin would kill anyone to get his fix. They wouldn't be good on a team either. Jhin would get his 4 shots off and Jinx would either leave him to die or kill everything including him with a giant rocket.
Also, I'm pretty sure no one can replicate Jhin's work. There is a certain beauty in his art that non other can recreate.
I could go on, but it is well past 5 in the morning.
