You should look at it in a different way. Why would you want to view RAW on iPad? You are not going to want to edit them fully on your iPad, are you? If you only want a quick preview on something other than back of your camera, then jpeg should do the job just nicely. If you want to, you can tweak them jpgs a little in something like Snapseed, but even then, that would be far from what I'd call "edits" for most part.
