I feel like the time for Austin Powers has passed.
Half the "schtick" of the first movie (i.e. the only one that was actually any good) was them poking fun at all the tropes of 60s-era spy movies, which hinged on nostalgia from Boomers and early Gen-Xers that were raised in the 60s and 70s. Few kids or young adults today would be able to understand the references, unless they're ditching him being a "60s spy" altogether (and if they are, what the fuck's the point of the reboot?).
Kill 1 man: You are a murderer. Kill 10 men: You are a monster.
Kill 100 men: You are a hero. Kill 10,000 men, you are a conqueror!
