Why just two? The Viper has 3 engine nacelles. Ive been contemplating building a viper myself and yes it would be an EDF. For a test project, 3 x A-10 nacelles could be used.
You could also use differential thrust for both helping to turn without isntalling a rudder as well as some elevator assist. Realistically speaking, you could set it up with no moving control surfaces....it would turn kinda slow maybe, but would work still. The two bottom motors would be used for stearing as well as up elevator input. The top motor would be down force for down elevator while the two bottom ones would slow down with the stick movement thus allowing the top motor to be pushing more forcing the nose down.
The small elevons on the wing panels might need the motor assist described above to get enouhg up or down movement...who knows...could be porgrammed to a switch to trun that on or off.
