Remember, if you want the best signal possible out of the Norsats, they will need to have 18V supplied to both of them full time. This can be done with power inserters or a modified multiswitch. The modified multiswitch is the more elegant solution for whole house systems. I would actually use the Motorola DSR-922(aka 4DTV) for my positioner to simplify dish movement and to get the occasional benefit of an ITC DCII feed that may pop up.
