For dos and windows the forward and back slashes have separate functions so I don't think it's possible to replace the backslash, which separates directories in a command path, with the forward slash, which distinguishes a command switch.
Also, what's the problem with zip files? You just need something like winzip to extract them. I can't imagine why that would be a problem.
Or why using \ is tiresome and using / isn't.
