So looking at the scope more closely and their documentation I do not think changing out will work as you have in your proposed change. I think you will need to rewrite the scope to use Reddit's API and register a "Installed App" and get a token and secret otherwise it seems without using oauth and having a registered app their API will kick back queries too although with a app and token/secret you can pass searches using their API and they will be via HTTPS.
