I think by its nature a book like this would have to avoid traditional action troupes. What would they do? Give Lois Lane a plasma rifle and have her leading the charge against Despero on a regular basis? (I mean, once in a while would be cool, but....)
But there are other ways to handle it. Consider the scene in Batman v Superman where Bruce tried to save the people in his office building during the Clark-Zod fight. He's not part of the action, the combatants don't even know he's there, but it's still a engaging action sequence full of physical danger and emotional beats.
That's how you handle it; Lois and her cameraman running into the dust and smoke and rubble as pissed off gods try to kill each other. Lois, dodging stray energy blasts and collapsing buildings, with a non-stop rapport for her live-streaming viewers, and helping people she comes across as she does it. Lois and her cameraman, trying to be capture a weapons sale between Intergang and Kobra on film, getting caught by henchmen, and having to escape.
It'd be different, which is a strength you play into. Coates could do it.
Oh, you'd absolutely have to use proxies. Using real-world people and events would be terrible.
And the idea that the media is politically neutral is a complete falsehood. There's damn few news networks left that are actually apolitical, most of them are strung out on one side or the other. That's not news, its an opinion, when the world needs facts and the common sense to come to their own conclusions. Which seems like a great reason to make sure your Planet comic shows everyone how it's done. Journalism as a super power for truth, that's your hook.
It'd be easy. Have Lois interviewing, say, the dictator of a small nation (we'll say Pokolistan) currently deep in a civil rebellion. Do a little research into Syria, see what Assad has to say for himself, and write your dialogue spewing the same propaganda for your fictional ruler. Have Lois counter with pointed questions, write solid dialogue that doesnt actively call out the other side.
After the interview you can have Lois say "What a f**king a**hole!" if you want to, but you've avoided telling your readers what to think. You've told them what Lois thinks, and provided some facts for both sides, and left it at that.
