What I do is copy the EFI partition with GParted. Have tested in the context of backup-and-reinstall. Where things might get dicey in your scenario is NVRAM. I'd expect it to be grumpy about four identical PARTUUIDs (be aware, that's what NVRAM uses, not regular UUIDs; compare efibootmgr -v with sudo blkid). Moreover, I'd expect any clone solution (including dd) to have the same issue.
Out of curiosity, if sda (for example) goes south, what are the boot loaders on the other drives trying to boot? Perhaps a rEFInd USB drive will suit your purpose.
