I'd remove the nib unit and use syringe or eye dropper to fill the sac.
Yep, that should work.

An Estie sac holds about 1cc, so overfilling shouldn't be a problem.
Might be a little messy with an eye dropper as the opening isn't much wider than a large drop of ink and the ink might dam up in the section. Syringe would be my choice - if you use a sharp one, don't put the point down too deep into the section as you will risk poking a hole in the sac.
Also, keep in mind that after filling your pen this way, the nib and feed will still be dry and won't want to write immediately. You could either lay the pen on its side for awhile or expel a drop or two back into the bottle through the nib using the fill lever.
