It's quite doable, but there is no compatibility between the two products - SkyView cannot accept data from, or send data to the FlightDEK-D180. In a full conversion to SkyView, the engine monitoring is mostly plug-and-play; largely disconnect the two engine monitoring cables on the back of the FlightDEK-D180 and connect them to the SkyView SV-EMS-220 module.
The biggest challenge is to install the SkyView ADAHRS module in a magnetically benign area, much like you did for the remote magnetometer, except that the ADAHRS module has limitations on mounting within a specific area related to the CG of the plane. Then the pneumatic lines need to be rerouted to the ADAHRS.
