I haven't tried this, but for the moving-a-drive thing, 'all' you should
need to do is boot a UEFI-capable live image and copy the efibootmgr
entry from the previous machine. The actual path to the bootloader isn't
going to change, because it's using a UUID.

If you want a drive to be transportable like this you could also move
the bootloader stuff around so it's bootable via the fallback path
(/EFI/BOOT/BOOTx64.efi , basically). See my blog post for more stuff on
the fallback path, the wiki article concentrates on 'typical' usage, not
complex scenarios.
