What if you replaced Singers with Klingons?

Odd question but I think it's fun to think about. I'm not super up to date on Trek lore but I feel like there'd be a big divide between Odium devotees and those who think he'd be dishonorable. Some Odium upped Klingons would be pretty terrifying. Can you imagine a Klingon on red mist? Fuck me that'd be scary since they pretty much already have a built in red mist.
