There are thousands of mice available on the market, and almost all of them can be used on a Mac. It's strange that anyone bothers to fix any mouse. Just buy a mouse that fits your requirements.
Magic Mouse was designed to be held with two fingers and moved with the wrist.
Personally I would never buy a product completely, diametrically different from what I need and then adapt it. But I guess some people like the challenge and I have no problem with that.
