How about removing the bearings from the EBB and make a hole with BSA threading to accept the standard campag cups?
As if I was capable of doing that? :(

How about removing the bearings from the EBB and make a hole with BSA threading to accept the standard campag cups?
The hole the bearings are in is probably bigger than the pilot bore for 1.37" threads.
46mm is small for an eccentric, even with 1.37" threads the eccentricity can't be more than about 2.5mm, so you wouldn't have enough adjustment to take up a whole pair of chain links, or even a half link, so you'd still be stuck with using somewhat magic gears.
The WheelsMfg unit cheats by having the eccentric in two halves, with the OD of the bearings overlapping the ID of the shell. The problem with this is that there is no positive register to keep the bearings concentric with one another, so the eccentric loadings might pull the two halves out of line, leading to high friction and short bearing life. Anybody who has used a lot of pad stack on a 3T Ventus knows that two 75mm long bolts won't stop the two ends of an assembly from rotating with respect to one another :)

Assuming the bearing spacing is appropriate, where I'm headed is machining the EBB so you can fit a Delrin liner in it.
What I'd actually do is buy Shimano cranks.
