I think you have a point. You may want to take a look at the SebArt MiG-29 design. It is also manufactured by Freewing. And here they fixed the problem that the Freewing Su-34 also had when it had to belly land: Digging in the nose and breaking it off. As the MiG is designed to land on skids all the time, that problem would probably be there, too.
The fix is done for the SebArt by including two medium length carbon fibre rods on both sides of the battery compartment, all along the cockpit. I still had it break there once, but not as violently as would have been expected from my Su-34 and Su-35 experiences. Maybe the fix can be transferred to the Su-35.
