Introducing Cox Gigablast

I understand that the first part of getting set up with the Gig service is to have someone from COX come out to look at the house to see how the installation will be done.  I'm wondering though, if without a site visit, you could answer whether it is generally possible when doing the new fiber wire install to the house, if the existing COX box (which has one conduit opening on the bottom), could be replaced with a newer COX box if there is a box which allows 2 conduits to enter from the bottom?

My hope is that the existing coax conduit would connect to the new box, which would also have a second conduit for the fiber cable.  I understand that this new fiber conduit would need to be run from the street where the new fiber box was installed, but I'm just hoping to only have one box on the side of my house for COX.  Is this possible?
