Not sure but you can't let Snyder do it or lump it on someone else without the chance to make big changes, could be an even bigger mess.
The other problem is do they want to keep the same actors, back story. A Universe reboot would be extreme but if you can't see a way back, maybe best to just do it.
Alternative would be a soft reset. MoS and BvS didn't happen. Wonder Women, Suicide Squad and Batfleck Batman are the start.
I guess you could pull a Star Trek reboot with some time travel stuff and conveniently write off anything you don't want to be canon anymore
