Tomas you found me !!!
My plan would be to build the basic airframe with retracts and servos, so I can get an idea of the weight, then figuring the max. diameter of the nacelles and work backwards from there. I may think outside the box on this one...maybe a true EDF is not the way to go with this one being electric...The big EDF's are amp hungry (short flight times) , expensive, and designed for fast jets and top speed..I would want more of a thrust setup, so possibly a shrouded prop setup, like a cut down 3-blade prop on 10S lipos in the 2000+ watt range, maybe a couple Neu motors, maybe some big Hyperion outrunners, not sure....I would need to get the nacelles first and do some experimenting on the bench. I don't need this plane fly @ 150 mph, it will cost too much in AMP draw I think. 80 mph would be scale speed and make me happy. Definitely going to go with the largest diameter fan/prop I can fit inside the nacelle.
