How About A New Browser?

Quality questions aside, do you guys think that Microsoft should just start developing a new browser alongside to get a clean break from the infamy surrounding Internet Explorer? Internet Explorer would still be Windows' default browser, but the new browser could be available as a separate download.

Microsoft could either pull another Project Mojave with the browser, and show people that they are wrongly prejudiced against it (as a lot of people just simply don't try it). Or, they could actually have another team working on a new browser, and follow through that path.

Would any good come of it?
