Either leave the low E string off, or slacken it right off to looseness.
Now tell us what the other five strings do when you dive, and when you pull up.
This might be a worthwhile experiment , as long as you consider that the whole system will be sharp once you slacken the Low E, and you'll have to retune a few times before your back to a relatively tuned and tension balanced system.
There will be a bit more tension on the other five strings while you are doing this, so things won't be quite the same as
having it set up with 6 strings. If you have the time and want to experiment a bit, you might learn something.

I agree.

Nuts are cut with special files of various sizes in order to create the accurate slots for the various strings. The slightness of the filing required, as well as the care and patience involved, are surprising to anyone doing it for the first time.
Excellent warnings,
Someone who does this alot has developed the muscle memory as well as the wisdom to tackle a job like this without touching the finish or the fretboard.

I'd suggest we stay specific ; everything done so far has been to do just what you are suggesting .
1. Fixing the tuner order
2. getting the bridge plate parallel with the body
3. readjusting saddle height and intonation due the correcting the bridge plate
4. raising the assembly to check for imperceptible rubbing
( it'll be up to whoever set's it up to determine whether to lower the saddles now or to bring the assembly back down that 1/8" once the key issue (most likely the nut slot) has been fixed )
Nick is so right about how it takes the lightest touch when working on nuts.
Now that the Low E tuner is correct, showing you the angle that will work best for the Low E slot ,
a tech can properly file it for best performance.
If someone in the past filed the nut to "work" with the angle it was at before...that might just be sharp enough to stop the string from freely moving.
Unless the slot needs to be lowered, that's not going to leave much material directly behind the break angle,
and some enthusiastic filing could lower that slot quick.
And it's possible that too much material has been removed from behind the break angle for this nut to ever work
properly .
I would recommend playing it ( we all need practice, eh?) while saving up for the best tech you can find.
Maybe G&L would even send you a new nut of your choice of material if this left the factory 'not right'.
I'll leave that to you and Craig et al to determine and resolve.
