The normal install for whole home would not swap out the SD box. The only case for that would be if it didn't support SWM, and since you got reinstalled recently I don't think you have that. To access whole home from there, you need an HD box. I personally would try to go with the HR34 in one location, though don't know if you'd get a deal, since you're still under contract. But, they may be able to make an offer.
