Could Google's HDR+ also use DNG instead of jpeg and combine those automatically? That would make it much slower, though, so they'd have to take 3 at most.

There's nothing technical that's stopping them from doing it. I expect third party apps to do something similar once Lollipop has a higher market share.

HDR+ does the processing immediately after taking the images. I would hope that the "HDR" step happens before any compression.
