Yes, it should. grub-efi does not require grub; all the EFI bits are in
grub-efi. Just having grub-efi installed should be enough for an EFI
system to boot.

(The intent of the recent changes is that when you update from an 'old'
grub-only install, you'll get grub2 and grub-efi both installed to
replace grub; this way ought to make sure that both BIOS and EFI systems
have a viable bootloader package available).


OK, I did it! I had to remove grub and now have only grub-efi installed and the system still boots :-)
