Ok, so Aqualung beat me to the punch and emailed back before I could call them. Here's their response...
'Hello,

So I guess that answers the question. But ultimately brings up another. Do they have a DIN first stage that would work with the Calypso second stage? That way I could just swap out the 1st stages and still hopefully save a little money.
