I don't think there is any interest though in a Commonwealth Athletics Championships or Commonwealth Swimming Championships- their main selling point is as a mini-Olympics.  If it isn't that, even on a smaller scale similar to the European Sport Championships, it's not worth it.

I’m not suggesting just athletics and swimming, but I think it’s fair to say there’s a world in which the games could exist without quite a lot of minority sports like lawn bowls and 3x3 basketball. If it brings the cost down of buying the rights and broadcasting the games then that could help increase its mainstream profile beyond just the UK and Australia. 

Maybe ending the games is the answer, which would be ironic given Birmingham was the biggest games ever. Personally I find the games become less relevant each time they come around, probably because the Commonwealth itself feels less relevant as time goes on and feels like an increasingly odd collection of countries.
