I believe you can buy a T&S adaptor for an M42 lens (poss other older mounts too), though they work out at ‘just’ cheaper than an EF mount cheap s/h T&S lens.
I think Canon have a patent for a T&S adaptor for an EF lens for M mount, but have never made one. Think about it, it makes perfect sense, the space required to mount the lens away from the sensor, and the increased image circle of a FF lens makes it a no brainier.
