The CS8422 looks to be a pretty cool chip. Stereo asynchronous sample rate conversion, so if I read correctly Kemper can still hang out at 44.1 as its own clock source and the output of the board can be whatever you desire (and synced to your interface/master clock).
The chip itself is only a few dollars and the eval board has a lot more functionality that we'd need so it seems plausible that a digital studio interface box could be made for non-bank-breaking money 
I only I had studied EE instead of chemical....
EDIT: Oh yeah, but we'd need 2 of them (one for each direction).
