Waid made a pitch to DC many years ago (that infamous one that included Grant Morrison and Mark Millar). It would be interesting to see that pitch manifest in some capacity ... tho it obviously won't be the same without Grant and Mark.
The marriage to Lois shouldn't remain (actually it never should've happened in the first place). Jerry Siegel himself disapproved of the idea (and I agree with him).

And it makes further sense when you read Alan Moore's 'Whatever Happened to the Man of Tomorrow?' in proper context. Yes, Clark and Lois got married in that legendary story ... BUT Superman also retired as part of that conclusion. So, if anything, one of the moral's to that infamous story was: If Clark and Lois marry, Superman ceases to exist.
Still, to each their own.
As far as Luthor is concerned, I don't think he should have a past connection to Clark. It's just not plausible that he wouldn't recognise him (that was one of Birthright's biggest flaws).
Having said all that, I'm not sure if any of this (creative team, status quo, etc) makes much difference. Considering the downward spiral mainstream American comics have been moving in (record-low sales, comic shops closing everywhere and the all massive lay-offs recently occurring at DC) ... it's difficult to have an optimistic outlook regarding the future of comics.
