When hardware fails basically anything can happen, it's undefined behaviour. In the old days of multi-drop SCSI, one failed disk could literally take out six others. Since you're running on modern hardware, the scenario that I would be most be thinking about is that the machine fails in such a way that it recognises disk 1 but hangs on boot, which just needs somebody to go in to the UEFI config and change the boot order in to make it come up again, (booting from disk 2).

Will you be able to reach some somebody on the phone who can follow instructions to fiddle with the BIOS? If so, then that might be enough. If the machine is in a truely remote location with nobody around, and you need a good guarantee of it continuing to work, it's probably not.
