Well, the bug has bitten. Now I can't stop.
Been thinking about a new crank design for a year now. See: viewtopic.php?f=3&t=96497&p=819164&hilit=pushed+cranks+space#p819164

Some sort of integration
4 arm (Campy 4 arm, not Zipp 4 arm),
(reasonably) low Q factor,
Apparently LOOK has a patent on one-piece carbon cranks (hasn't BMX had the design for ever?), so full integration is out.
I tried to explore a thin bearing that will fit a PF30 shell to allow a bigger spindle than 30mm. That didn't go very far. I might have to explore a larger frame BB shell. Fortunately, commercial feasibility isn't a factor, so anything goes, for brainstorming purposes.
That aside, I need to figure out the best JOINT mechanism for this crank, on the drive side -- the inherently bulky joint will overlap with the bulk of the spider. At least we can have a sleek piece on the non-drive side.
Hirth is out as it's more appropriate for Steel. Too many carbon/metal interfaces will defeat the purpose. Probably no spline either.
As stupid as it sounds, i am actually thinking about something along the lines of a square tapered structure but in carbon. Alternatively the spindle could be round with several smaller fastening bolts from different angles (4-5).
Any input welcome.
Sorry for the sh*tty drawing.
