A very common cup diameter is 29.6 mm.

That’s a tricky spacer to make.
Which leaves you with two options:
- track down a cartridge bearing with a smaller OD while still having a useful ID.
- tear down to bare hub, and rework the hub.
And you need a hub with a central cavity large enough to house a support sleeve to go between the inner races.
As far as machining goes, it’s a quite nice job. But it does take a fair bit of time.
