(Nearly) full tickless operation in 3.10
That's possible right now and would avoid duplicating all the drivers, but it seems to never have gotten popular for some reason.

If you have a hard disk using MBR, this image would be embedded in the gap between the end of the MBR and the start of the first partition. With a typical layout, the this is normally only 31 KiB. Could a minimal kernel be built to fit into such a small space?
If you're using GPT then things are easier: the conventional gap before the first sector disappears entirely, and is replaced by a dedicated partition for the boot loader (misnamed the "BIOS Boot Partition" in GRUB's case). This partition can be of any size, so you can build as complex a kernel/rescue system as you like as a "boot loader"...
