That AC quote about them playing "at least one show in April" makes them possible. And I'm pretty sure that Goldenvoice would try their hardest to book both acts instead of one or the other.
Also, that Pitchfork interview with him talking about how much enjoyed Coachella and seeing Daft Punk there makes me think he'd do it.
From that interview
Daft Punk at Coachella
Definitely my favorite show recently-- and ever, probably. I like their music a lot, but I wasn't expecting anything (not in a bad way) that night. I was more curious than anything else. We were way in the back of the (huge) tent, but it still sounded amazing, and the bass was really tight like in a good dance club, and that seemed impossible for how big the thing was and how far back we were. The setup was epic, and the whole thing was set up in the shape of a triangle. They showed a big screen of them closer up for those of us way at the back, but you couldn't see their hands, so it was just these two guys dressed in cool future-suits bouncing softly and pumping their helmets. It looked really, really awesome, and it got me excited: The way they looked, the way the songs moved, and everything just totally ripped.

I also see concern with the size of the Fox in Oakland for him, but as long as the crowd is there for more than Comfy in Nautica and the first minute or so of Bros, I think that it will be a good experience.
