Yes, but it would be somewhat dirty.  Here's why:

Linux-libre contains a superset of modules and also their modules.alias
and modules.devname contain a superset of modules compared to the initrd.

That means

(1) modules.alias would contain aliases which map to modules which
don't exist.  Since we don't for-each it, who cares.

(2) modules.devname would contain devnames for modules which don't
exist.  That means the boot code would create files in /dev which,
when someone accesses them, would try to load modules which don't
exist - and then the access would fail.

Technically both are not bad, but (2) is bad "UX" practise nowadays - and
not done in the Linux world any more since udev exists.

I can still remember the days of 8540 entries static /dev filesystem (as in,
really on the hard disk), 7000 of which didn't work (or even valid for this
system type :P).

If something goes wrong, good luck finding the needle in the haystack
(which /dev file you can use to boot).
