Yeah, we already have decades of prior-art for what can be done if you take a flying machine, remove the pilot, and then aggressively specialize the aggression, which are missiles that can experience up to 100 gees.
But in a completely flight envelope and range requirements. It is not a coincidence that missiles that are higher range (cruise missiles) have not retained the extreme maneuverability of short range, solid booster powered ones.
It's all a matter of trade-offs. If you design the airframe to withstand higher G forces that makes it heavier. Thus you sacrifice range and payload. There are very few real world scenarios where the ability to pull more G's is actually helpful.
Making the airframe even more rigid and capable of resisting extreme forces also makes the wings and fuselage and control surfaces much more heavy, so you end up in diminishing returns. Look at the 'final' revisions of the F16 sold for export that have had all sorts of pylons and conformal fuel tanks stuck onto them, compared to the original prototype. And that's just making it more heavy and laden down with stuff, not more capable of extreme maneuvers.
