Burt Rutan already has a fibreglass, two-engine A-10 alternate flying. Not quite as capable (lower payload, less range/less flight time), but survivable.

Seems like another in the USAF lonnnnng series of “Let’s “study” another design to try and create a perfect airplane for everybody, rather than decide on a “good enough” plane for each job, or just build enough airplanes already flying.”

Are you referring to Scaled Composites' ARES from the early 1990s??

If so, it was a single engine aircraft.

You may notice that this project was dubbed "Son of ARES"?
