I think it's about time tech cameras to go electronic, with electronic leaf shutters and electronic integration with the digital back.
What you would get is lens/tilt/shift movements registered in the EXIF data, you would have shutter control directly on the camera body (no flash sync cable).
A future CMOS digital back with wide angular response could show live view and use the tilt/shift movement information to auto-apply LCC from an internal database. It would even be possible to apply it live so the live view would not have color cast or vignetting. The live view could also show dashed lines of the image circle so you see when you're getting far out.
That would mean no more LCC shots, no more flash sync cable attach/detach, and no more fiddling with mechanical shutters. Although such a camera can be backwards compatible with Copal shutters of course. You could still have a smart lens board / mount that can report that the attached lens has focal length X (which gets registered in the EXIF data) and is using a mechanical shutter, and you could have flash sync attachment in the board itself so you don't need to care about the cable. So even with a Copal shutter there would be no flash sync cable fiddling (except cable release) and LCC would still be automatic.
You could have one small battery for the camera in the camera body itself, and one in the back, or you would have a larger battery in the camera body so it can power the back too (ie Hasselblad H backs).
While I'm myself quite okay with working with a 100% mechanical camera myself (I find it a bit charming actually, even ground glass focusing), I think tech cams would gain from becoming a bit more user friendly and quicker to work with. One of the best Swedish architectural photographers uses a D800 for most of his assignments, not because it's much cheaper, he does have a MF tech cam too sitting mostly unused at the office, but because the D800 is faster to work with. With electronics the tech cam would be just as easy to use and fast to work with, but with more flexible movements, more focal lengths to choose from and higher image quality.
A focal plane shutter has the advantage that you only need to pay for one shutter, but I think the disadvantages are too severe 1) increases flange distance, 2) introduces vibration problems forcing the camera body to be very heavy. Therefore I'd like to see an electronic leaf shutter with sane integration ie not a bunch of cables and a home-made looking gigantic controller box on the side which cannot handle outdoor conditions. And as said, if you're on a budget you could have legacy Copal shutters on one or more of your lenses.
To me the dream camera would be an electrified Linhof Techno with a 48x36 to full-frame CMOS back with wide angular response, with "smart" lens boards, ie electrical interface to support electronic shutter (the DHW/rollei seems like the best shutter today) and programmable to report lens model when a copal shutter is mounted. CMOS live view makes view camera design (focus rail, tilt/swing built into the body) more feasible than it is today when you need to master ground glass focusing. IQ250 is a good start on that, but we still need larger sensors and wider angular response to make it a tech cam winner.
