Don't see why not. If the high-altitude designed B-47s could do them
(admittedly,
with some serious wing fatigue problems as a result), then the low-altitude
stressed B-1 shouldn't mind.

It's not a stress issue, it's an excess thrust issue. The Bone may be able to
pull off an immelman,but I'm betting you won't find too many pilots eager to
test out that theory.

By the way, the B-47 could do many things niether the B-52 or B-1B can do.
