Have you guys got any ideas or shortcuts?

Ed,
Yes, that's a lot of drilling. The 1/2 inch (cement?) backer board will destoy their hole saw bits, unless their carbide tipped. There is another option, and that is to do it from the inside. Dirtier for sure, but probably quicker, and therefore cheaper. Then there is the plaster work to go over the holes from the inside.
BTW, don't blow in Fiberglass. It doesn't perform like cellulose.
