Yh right, two characters with a combined bounty of 3.6 bil that held their own against two Gorosei are fodder
I see what you're getting at but I doubt that's the case. For one, Dorry & Broggy don't seem like the type to lust after such tings. Sure they might want to get stronger but I doubt they'd want to achieve it that way. Moreover at what cost? Shorter life-span, mind-controlled and ordered to kill people dear to them? Doesn't really compute tbh.
Also keep in mind that as opposed to Linlin who's a mere mortal, Imu is a god so can't really confine him to what Linlin is or isn't able to do.
