Justin,
Very nice panel! The removable iPad with storage space is a nice feature I haven't seen before.
These are a few comments from my viewpoint:
Its nice to see you included the new SkyView COM radio. It took us a little while to start shipping them, but the radios have excellent specs and performance in the field. You will love the database driven button-touch tuning.
Dynon will gladly sell you a D6; many customers want one as a backup and it does offer independent software and battery backup separate from any other PFD it is added to. A dual SkyView is designed for IFR redundancy and is more reliability that most GA avionics systems flying, but the D6 by definition adds even more redundancy at a fairly low price.
That being said, I personally fly behind a redundant two ADAHRS SkyView without a D6. The redundancy design goal of SkyView is that no single point failure reduces flight functionality. For example, loss of a data line (short or open) just transfers data to the second line. You do receive a warning so that you know to fix the failed data line. Even the loss of a display automatically transfers all control to the second display for continued flight information and autopilot functionality.
SkyView software has an excellent history in regards to the extreme rarity of even single-display in-flight glitches. Some units had a component hardware failure which we replaced through a service bulletin, but that has not caused any two screen failures. We are very open in our forums to the entire community and do not hold any information back. If you ever have a question about a failure discussion on our forum, please ask us for any clarification on the end results and causes.
As you are planning the location of the various SkyView components, do you know we have dimensional drawings for everything? You can find them at

Please let us know if you have any specific questions.
