It's easier to fix the USE flag differences by hand.  And I don't think
it's necessary to copy the no-multilib files to /etc/portage/profile.
Just rm /etc/portage/profile and re-link to the no-multilib profile,
adding those USE flags you need (which probably won't even be all those
USE flags included in the desktop profile.

I'd say the rest of your surmising is correct.
