I've considered but can't see doing the following:
1. mash an English cartridge in there
2. do the Phil/Shimano mod (would have to find someone with a bench grinder)
3. giving up and accept the wobble
I checked on retapping to Italian thread and it's like $150.
UO-10 ≠ $150+ modification
What would you do?
I think you're chasing the wrong solution.
Find a high end shop that has a Mavic BB chamfering tool.
The Mavic SSC Bottom Bracket was incredibly high end. That group was more expensive than Campy Record at the time. Lemond won a tour on Mavic SSC, and Sean Kelly won Paris-Roubaix on it. Its good enough for any bike you put it on.
The Mavic BB works with a compression fit. The Mavic chamfering tool will bevel out the threads and you then insert the Mavic BB. Its a great solution for bikes with weird French BB threading or any bike you want to put a high end BB in but can't source.
You can ALWAYS find Mavic Bottom Bracket on eBay for a song. Very few people want to commit their BB shell to a Mavic BB for the life of the frame. However, the Mavic BB is a world class BB. Think of it like a Phil Wood, only more eccentric.
