Dave, I'd consider opening up one or 2 of the black squares on the fuse side ahead of the inlets (the black trim scheme) and also look at adding a NACA duct on the bottom.
I'd run a bell-mouth and no intake ducting (or perhaps very short ones from each side).
I don't know how much intake area there already is, so I don't know how much extra area is needed; (do you have one to measure?)
These are just some

ideas and may not be feasible.
I have the CARF Viperjet and marvel at the lightness and strength. Gotta be an EDF option on this one, somehow....
