Your idea adds a few mm either side of the hub as a min taking it up to 65 mm plus, a 65mm hub will not go into a 62mm hole how ever hard you push!
As I say my discs are funny the bell almost covers the hole hub lip the drawing is very crud it's obvious the lip that sits inside the wheel will have to be the same size as the wheel. As there's very little original hub lip there this should not be an issue. If I can't buy something that will work give it till end of summer ish and I'll post a picture of what's been made
