We wouldn't need a Year One retread. We all know the origins by now, they could take a BTAS approach and just set it somewhat early on in Batman's career and go forward. No origins necessary.
Batman being written as a jerk would still be a problem, so we ultimately need to make sure writers are on board with not writing him that way. But doing that in mainstream canon as is does require ignoring a lot of terrible OOC moments for him that added up, and some fans and writers simply don't want to let that go. I'd prefer no baggage at all.
I personally don't care about ditching the various spin-off characters since I don't care for most of them anyway, but thankfully I have no power to do that. I'm just bitching
