I guess these are the basic issues:
1. Strength - anybody's guess - but if the welds are already failing...
2. Geometry - equally hard to assess whether important distortion has taken place, you might not know till you try and run it.
3. Cosmetics - you might be able to dress the welds and make it prettier but it's never going to be lovely.
4. Money. It costs a lot these days to build up a good engine. Given the risks above why wouldn't you start with the best parts you can get your hands on?
Rubies also had 3-bearing engines, why not just rebuild one of those? That would be my choice.
If hell-bent on a 2-bearing, seek out a better casing, they are not hard to come by.
And keep this one in the you-never-know pile. I have a scrap case and keep on finding uses for it.
