Using 5-axis IBIS to emulate or partially replace tilt-shift lens functionality?

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....

The idea for a tilt shift sensor is not new to me either. It would be hard to create that with the IBIS mechanics as you mentioned already. With the "focal plane" shutter before it even harder. But the Mamiya Super 23 6x9 cameras had a rear side that could be tilted. I can imagine a rear side of a mirrorless digital camera with some shift and tilt movement that has the sensor + shutter integrated. Another idea is a focusing sensor + shutter part similar to the focusing film plane of again Mamiya cameras, the Mamiya 6 folder camera range. A concept that was later also used in the Graphic 35 Jet and the Contax AX.
