Good progress! I do see some similaritys of my concept
In theory you could place 1 fan in the centre and a fuse along the side (like a simplified Rutan Ares). That might be a good option to create good batterie space for high power setup (for a single fan jet) and good space for hardware.
With some creativity you can increase wing and elev mounting strenght as well.
I often noted closing a bifurcated exhaust on one side to gain intake efficiency on a Pyranha or Sniper like Ares.
Just a thought
at Luft46 there is a jet designed like this but cannot find the model in short time notice.
