Need 2 Unit Mount for Livescope and Lowrance HSD

[Quailtail]

I have decided to take the plunge for Livescope. Need a 2 unit Stacked mount for the Livescope screen which will probably be a 12 inch unit and my 9 inch HSD. The issue I have is that my Ulterra is mounted in the center of my bow. I have 22 inches from bottom of boat to the shaft of the ulterra when stowed. See pic. I am looking for suggestions from those more experienced in this sort of thing than I. Don't want the Livescope too low but on the other hand don't want it to high to be in the way while spider rigging. Whats out there that may work under these circumstances. Don't know how to turn this photo.
