(OP)
What alternatives are there for adding horizontal reinforcing to unreinforced masonry? Through bolting steel plates, epoxy anchoring steel plate to one side?

1) When the cuts are made, any axial stress present in the wall will migrate to the rear face shells. It usually works.
2) When the repairs are complete, the stresses will be different from those typically assumed in a non-repaired wall. Some of the stresses from #1 will be locked in.
2) For the duration of time during which the new bars are being installed, you've got a hinge mechanism within your wall. I've provided temporary lateral bracing for this reason in the past.
Out of curiosity, why is FRP off the table? That would have been my first choice.
Do you require a minimum amount of vertical reinforcing as well?
If capacity isn't a problem and the only issue is code compliance, I'd try to find some non-invasive way to solve the problem. Maybe attempt to justify satisfactory performance and seek a variance etc.

@KootK Thanks for the extra considerations. I add things like this to my mental locker so that in the future I have a more knowledgeable and thorough process when analyzing and designing.

Depending on how it is designed and detailed, FRP can be woefully non-ductile.

Agreed.
