(yes)
hmmmm....
think of a mirrored image on how the turbo connects. Instead of joining the runners perpendicular (for a wastegate) run another lower pair of runners angled down to join the wastegate. So you'd have an upper pair that looks roughly like > and a lower pair that looks like > but they're angled up and down respectively to give the best flow possible. I'm just thinking out loud on how I'd want to join the pieces and how far apart to make the join.
I imagine a smooth transition between the two would yeild the best results, however I wonder if that would cause un-needed turbulence in the exhaust flow. I suppose it doesn't really matter as it's the temperature and pressure difference which drive the turbine, and turbulent flow: flows faster than lamnir, but I just can't seem to figure out how the exhaust will work in the manifold.
