I've only now just thought of this, but what about a John Wick map pack?
House of Transparency (3rd Movie)
John's House (1st Movie)
Russian Church (1st Movie)
Docks/Helipad (1st Movie)
Museum (2nd Movie)
Continental (All Movies)
Minting Facility (3rd Movie)
Just some ideas, but they'd be really fun. While it wouldn't be as badass as Keanu Reeves double-tapping fools left and right, it could still be a lot of fun.
