My lineup would be:

Green Lantern - Tom Cruise
Flash - Armie Hammer
Superman - This one's difficult since Henry Cavill did (I thought) such an amazing job
Batman - Scott Adkins
Wonder Woman - Gemma Arterton
Aquaman - Bradley Cooper
Martian Manhunter - Bruce Willis

Directed by Guy Ritchie

Honestly weirded out that I can see it, but I can actually really see Bradley Cooper as Aquaman. No idea if he can play serious Characters, too, but actually...that´d be kinda cool..

I thought he was great in Limitless, and he was pretty serious throughout most of that film

Only ones I really take issue with are Green Lantern pic related and Martian Manhunter

I'm not sure I can see Bradley Cooper as Aquaman either

Bradley Cooper's got that sort of cool-headed slacker look to him, which is kinda how Aquaman struck me in his New 52 origin. He can also be pretty serious and play that sort of leader when necessary, though initially he was my choice for Flash. Maybe Armie Hammer and Bradley Cooper could switch places.

I'm honestly feeling more tropical looking Khal Drogo Aquaman
That being said I've never really been a big fan of the character and therefore know nothing but barebones basics about him and wouldn't be suited to make the Magnum Opus of Aquaman casting picks

They could always make him a huge Entourage reference and cast Adrien Grenier

Well I mean the original picture I posted if I'm already saying something you were aware of, sorry was the cast set for a scrapped Justice League movie in like 2005 that was going to be directed by George Miller, so they were very real possibilities.
As far as casting now goes I'm not up in arms about any of them really. I can see most of the actors playing most of the characters.
From what I've seen of Ezra Miller I have no doubts that he can pull off whatever they ask of him in that role and do it well.
I've got faith in Ben Affleck as Batman, seen and liked Henry Cavil as Superman. Don't really have strong feelings about Gal Gadot since I've never watched The Fast and the Furious franchise. Haven't seen Ray Fisher in anything, but he definitely looks like Cyborg, minus the cyborg part of course...

Am I missing anyone?

I don't think they've really announced anyone else

okay then

As a side note the page I found that picture on was a speculation asking "Will the Wachowskis direct The Justice League?"

I sure as hell hope not
