The one real change I would suggest is to eliminate the longish bent duct routing, and add another half barrel at right angles to the original set. Cutting the end of a half barrel to fit the side of another is not that big of a deal, and plenty of screws will hold the assembly together securely.

Glenn Herbert wrote:To clarify, I haven't built a multi-angled barrel bell, but I am sure that it wouldn't matter as long as the top is a continuous level. Matt Walker did it for a restaurant some years ago, with more than six barrels, and two right angles if I recall correctly.
I would give the exterior chimney a drain so condensate would not have to come back inside to be handled. I would use a tee and not an elbow at the base of the chimney.
