A supermaneuverable U-2 would be... interesting. I wonder if that would reduce pilot workload or increase it? The engineer in me would suggest a robust automatic flight control system system instead, although considering how insane the procurement process can be, I'm admittedly not all that confident it would save money in the long run.
I'm not a engineer but it seems infeasible to me to create a U2 variant with wings strong enough for such maneuvering. They shaved every ounce they could off those things.
