Okay, so this would be a big gamble, but it's not my money so why not?
"Arrow & Canary. (or whatever; title doesn't matter)" By Mark Russel and Chris Samnee (or people sorta kinda like them). The book that'll offend you and everyone else!
The industry, DC especially, works hard to be apolitical, and with good reason. So make Ollie's book the exception, and go in hard on it. Tackle current events and politics and social issues. And voice those debates through the arguments Ollie has with John Diggle. Ollie's the knee-jerk liberal, John's the traditional conservative. Make sure neither of them just toe the political line and ensure that they're on the other side concerning a few topics, and make both of them disgusted with their own political party. Make sure that both Ollie and John get a "win" over the other occasionally, but usually no one convinces the other. Make them both have good points, and also a few opinions that are just dumb and hypocritical. Subversive and offensive by intent, but being fair handed with it. Ollie and John should be likable despite both being jackasses when it comes to politics.
And go retro with the style, like Samnee's Daredevil and Captain America. Golden Age inspired in art layout, to the point stylistically and narratively, with no padding. Each issue stands alone but contributes to a larger plotline that's wrapped up in time for the trade.
So here's the set up. Ollie works "officially" as a bounty hunter. Widely recognized as the best hunter on earth, Ollie goes after the FBI's most wanted and other criminals the law is looking for, does tons of pro bono work (mostly pro bono, actually), and has targets of his own as well; corrupt politicians and businessmen, the usual type of SJW target. He's not affiliated with the League or the heroic community at all, outside of Dinah and Hal. He and his support crew, consisting of Diggle, Emi, Roy, and....a guy in the chair (not Felicity, but whoever else) travel the globe helping out and stalking villains and exposing corruption within the system, making just enough money from bounties and raids to stay in business, and if there's anything left over it goes to the needy. Dinah is the lead singer of the Black Canary band, moonlights with the League and other hero teams, and she and Ollie are recently married (again). Since they both travel, they don't always spend a ton of time together and get plenty of "solo" plotlines.
Ollie's the minimalist hunter, no silly trick arrows or bright green tights, everything low-tech and functional except the bow. That should be high end, "military prototype" types of advanced, but not quite into the realm of "pure sci-fi." A few trick arrows, like explosives or net (not as silly as MCU Hawkeye), would be used but no boxing glove arrows (sorry). Dinah's arguably the greatest martial artist alive, excepting maybe Shiva and Richard Dragon, and would use her powers in more creative ways than just "big area of effect" cones. Whistling like bullets, mimicking someone's voice......there's a lot more her scream could do than just "bring down this building."
And the hook to get people to issue #2 and beyond.....Dinah just found out she's pregnant.
