Would we be able to use the measles virus to reset the immune systems of people with autoimmune disorders like MS or rheumatoid arthritis?

This might be the dumbest thing I've asked out loud. But I'm really interested in how the measles virus causes immune system amnesia, and if that specific aspect of the measles virus might be able to treat autoimmune disorders.

obviously, this has the drawback that the patients would be infected with measles. but would their immune system stop attacking their own body?
