HDX 16x16's with Slate Digital VRS8?

[DeHaanStudios]

I know it has not been released yet, but I was planning on getting the Slate Digital VRS8 package to play around with, but was wondering if I would have to use the line outs to go into my 16x16's or can it be hooked up via PCIe/thunderbolt as a interface and be used withing PT at the same time as pulling channels from the HD I/O's given that they are both set to the same rate?

Forgive me... I did try and search for a topic about this but I must of miss typed the first time cause it said no results found, but when I searched again, the main Slate Digital VRS8 thread came up. Delete this if needed, but the main thread didn't cover my question and the last post is from last year.
