1. You can't really have a tilt&shift extension tube. The mechanical components will be so large, you won't be able to use most of your lenses at any reasonable focusing distances. Also since most native lenses only barely cover their native sensors anyway, you wouldn't get much tilt and shift out of them. You can maybe adapt a FF lens onto a APS-C sensor of the same system but then again, short focal lengths won't work at all since they'll probably focus somewhere inside the lens. Longer lenses will work but that's a really limited application.
2. You can make a tilt shift adapter and use FF lenses on APS-C and MFT mirrorless cameras. These things have existed for years. You can even buy one for medium format lenses and use them on full frame mirrorless. No idea if there is a medium format to DSLR tilt-shift adapter.
3. Hasselblad had a tilt shift teleconverter for years. Teleconverters work by making the image circle go larger, which lets you move the lens around to benefit from tilt and shift capabilities.
