Well, but if you have no way to acquire the password you are in
trouble. You have to think about the UX at some point.

You'd have to rework systemd-suspend.service (and similar services) to
transition to your initrd fully, then run systemd-sleep from there I
figure and then maybe have a drop-in /usr/lib/systemd/system-sleep/
that unlocks the root fs. But it's not going to be nice if there's no
UI support.
