Multicam With HPX170 and HPX250 using Samurai Blades Will it Work?

So right now I am looking into getting an HPX170 to match the HPX250 I already have, I looked at DLSRs such as the GH2 and 3, as well as 60D and others like that, and found out that there would usually be problems with audio syncing and overall look difference, so they wouldn't exactly match, I will be shooting audio to an external recorder specifically the Edioral R-44, so I was wondering if I got the Samurai blade for both the HPX250 and HPX170 and shot them both in a multicam scene, would the footage match, and if not would it be close enough that I could match it in post without any problems, like via Color Correction, because as I understand it the 250 is 1080p and 170 1080i, as well as the 170 having a less good lens in terms of low light, I will be using the Pro Res 422HQ setting on the Samurai Blade,
Thanks!
 
You can get the colors pretty similar. But sharpness at 1080i or p, good luck. HPX170 is not a 1080p cam. Quality degrades once you set at 1080i. Even if you capture to a desktop Mac or PC w/ uncompressed 1080i HD-SDI, it will not magically recreate what's not there to begin with. Not sure if you can handle the softness by having to stick to 720p on all the cams. Overall HPX-250 is simply much sharper than the 170 overall.

I don't know why you would even bother w/ dSLRs. They're just not designed for long events work that require servo zoom and focus. The short recording time, potential overheating, lack of real SMPTE TC are just not worth it. Yes you can sync w/ audio. But good luck. I tried it and it took almost a day for FCPX to analyze all the audio waveforms on the 12 cams. Complete disaster. Lesson learned the hardway.

We shoot events all the time with the hpx300, 250 and 170 all the time. I would say our biggest hurdle, which is not really that big of a deal is the difference in the look of each lens. Color match is fairly close but any difference is usually hidden in the different lighting areas on stage and in the audience. We jam timecode between the 300, 250 and the Sound Devices recorder and put a good mic on the 170 so we can sync it in post with FCPx. The only issue with audio is we try to keep the mic on the hpx170 as close as possible to subject so we don't have audio issues dealing with mic-subject distance. For every x amount of feet results in x amount of drift.
