I've never seen an offset or corbelled chimney that didn't exit the roof at the peak. Has anyone seen one?
Yes, I have, but it was still corbelled toward the peak. That makes sense though, you will produce turbulence and higher and lower velocity areas where the corbelling is especially on an unlined stack and this will have the effect of dropping much of the particulate (glowing or otherwise) out of the exhaust stream.
