That's kind of along the lines of what I expect - basically a 23" iPad Pro/Air body on an adjustable stalk of some kind, much like the new displays (with swivel, if possible). An iPhone-thin display would be even sweeter, but then we run into the 'guts' problem, which your base idea would solve. Not sure they'll ever go that route again (since half the point of the sunflower base was the disc drive) but it's a fun thing to imagine.
Then again... there
were all those patents around the beginning of the year showing off some weird dock-able single, curved sheet of glass concepts.
