[Konvas] 180 degree mirror shutter on Konvas 1M?

[Steve Zimmerman]

I saw this 180 degree mirror shutter on ebay.  Is I guess it is possible to install this on a Konvas 1M and get motion just like an ARRI cam?  I thought the shutter was 150-something degrees for a reason?  I wouldn't want any "Saving Private Ryan" vertical smearing.  If not, I'd like to upgrade my camera to this in the future.  

Thanks everyone,
Steve Zimmerman
