Why not I say.. worth a try
This took all of 45 minutes to draw, so why not?
The firewall here is for a Dragonfly.. I have one that runs well and the clunk works (small silicone from Texas Timers..). I set it back a bit for CG reasons. The h-stab is enlarged 10% for a 21% area increase, which is still small. But with the CG forward it will be fine. Not I do not plan to use the full flying elevator! 3 x HS45, Lemon Rx and 300 mAh 1S Lipo plus step up regulator will take care of the flight pack at about 45g.
When I get to building this, I promise to build quick fast and dirty for a change just to test it out. It's kind of a challenge to myself you see..
Ugh, this looks too small. Oh wait, that's only a thumbnail.. I get it now..

The area looks small, but two of those tail booms have a lot of side area combined - and the lateral area ahead of the CG is very small so she'll be fine. The center mark ahead of the spar is 12% static margin, the stab area is small so the neutral point is almost on the wing center of lift. My biggest worry is seeing it in side view!

Yep, they are hard to see. My Sig Wonder is like that. I have to fly really close or I lose it when it goes full blast. Now that I mention it, your plane is pretty much like the Das Wunder with booms.

Neon Yellow will show up if the wing tips are done in that color
RED on the tail booms will hold it color for about 100ft + or so before
they turn to brown then black at 150ft. Neon colors do well with sun
light on them keeping the color visible a bit further out. Yellow will turn
to white over a distance. Of course at 200ft. the whole thing is one black
profile.
