HELP - AIR SEALING a Continuous Stone Interior/ Exterior Wall

I just recently audited a home that had a blower door number of 11,684 CFM50 and/or 11.81 ACH50. And of course one of the main air infiltration culprits was a stone face wall that was continuous on the outside and inside of the building envelope. The basics as I see it is this: the 1/4" stone joints allow air to freely flow into the house.

Does anyone know of any good methods to seal a high-end stone wall air leakage like this? 

Thanks.

Below are some photos:

Air sealing a wall like this must be done with a vapor diffusive material or you will get spalled stone faces from sealing materials holding water. I recommend mixing hydrated lime with local clay soils, this is the way they have been sealed for millenia. Vapor open and beautiful. Do not use cement based products to fill the gaps as these are not vapor diffusive.

I've drilled wood window and door jambs on double wythe brick walls and then dense packed.  Helped a lot.  Dunno if that applies to your job.
