Mozilla would be happy to replace Qt/Cocoa/... with HTML+CSS+JS (or XUL). So it's obvious they'll be highly reluctant to have the exact opposite.

Microsoft once tried this in Windows 98 (thanks tightly-integrated IE) - and fairly succeeded. Since then, the attempts to "bring the Web to the desktop" are fairly constant.
