I don't think it's technically possible to even replace Finder. If you type "open ." in terminal, it will open in Finder.

There is not an optional "set this as default" like browsers. Something we should really push Apple to do. Finder is trash.

It’s possible to get pretty close. For example, Forklift’s instructions (go to https://binarynights.com/manual, search for “Default File Viewer”) nearly replaces it, except you still have a Finder icon in the dock.

Is it not possible to alias the open command?
