I'm not sure where to put this idea but I feel it might fit best in here.

After doing some "research", I could find precious little on this subject.

If there could be a user-controlled function (either hacked though Magic Lantern / Sony OpenMemories) or officially enabled by having the sensor tilt and/or shift manually instead of the lens? I know that very slight movements in a tilt-shift lens can have extremely dramatic and noticeable effects.

IBIS does not have enough range of movement to be significant for tilt/shift.

The Scheimpflug principle predicts the change due to tilt, and it is bigger than you'd expect, but not that much. IBIS is only intended to relocate the image to it's reference position during a shaky exposure; just how big are the shake blur circles? Usually, not more than perhaps a dozen pixels -- so that's the order of how much it's designed to move.

On the other hand, it is possible to implement tilt by tilting an additional optical element, and not the lens, so there are creative things one could do that way....
