Edit the web.config file?
Yes it's possible, after all web.config is just a text file

Is it feasible?
No, it's not a good idea, realize that any change you make to web.config will result in the application being restarted on your webserver. This means all the sessions go bye-bye. The best way to store dynamic data like this that doesn't have to be in web.config is in a database, or a xml config file you can parse at runtime, without interrupting the flow of things.

If I were going to create something like this, I'd probably create my own class to actually store the data. This class would be able to be serialized/deserialized into XML using the XmlSerializer class.
