I've been refining this in the FEA and CFD software I use here.. finding that rather elusive sweetspot between the best in aerodynamics and the stiffness/weight I'm looking to maintain.
I've kept the cap bolt pattern the same as existing 3T stems such that it could be used with them, but there's to be a much more significant aero advantage to using the whole stem.

I'll be cutting moulds to make it from carbon fibre within a couple of weeks and will post pics of the prototype.

Stay tuned :)

Did this ever get built?
