I have been saying this exact thing for ages - WW and WW2 is first world war and 1984. Let's hope WW3 is early 00's - So you can ignore BvS etc
Green lantern corp can be any time or place - i would love the 70's and set in space, so fun. The sequels can too - you can forget BvS etc
AM, under the sea, can feel separate. you can forget BvS etc
Shazam, we have no idea but let's hope it's ambiguous on when it is set - therefor it could be retconned to before BvS.
MOS2 should be set in the time between mos (2013) and BvS (2016) there is so much potential to work with.
This will take you until 2025 and hopefully made $$
All the while, the reboot on the other side with Matt Reeves is well under way and a new universe is the focus and can be expanded upon.
