Any way you could change the fittings on the BIX to 3/8" (assuing that's what you'll use)? It isn't exactly the best thing to step up and then subsequently step down the size of the tubing. It will hurt flow rates. You could try and get your hands on a DDC with a modded inlet. You'll get 140 gph and like 9.5' of head. Should cost less than 2 CSP Mags, and it validated as a reliable pump.
