Would it be possible to make a hybrid 4K 3D movie?

[Just_Discovered_3D]

So there are present-day 3D projectors that will play 4K in 3D? Even without blurays that could still be useful for gaming.

If the MVC encoding scheme works by identifying the differences between the right eye and left eye frames, if only there a way to work that in reverse and use MVC's "list" of differences to create the right eye view from the 2D on a 4K disc.

The point raised here about professional 3D conversions is well taken, as from what I've read the conversions have been known to even alter scenes to make the 3D experience better, though I would be willing to watch such a 4K 3D conversion
