Override the default package.json generated by ember-cli addon

We create a lot of ember addons for internal use in our web application. To suit our needs we make minor modifications the the files generated by ember-cli when creating addons such as the package.json, ember.try, ect.

Currently I am exploring the possibility of overriding ember-cli's default blueprint for generating addons to streamline this process, but have had little luck finding any resources on this.

I was able to override the default blueprints for our routes and controllers but doing this for the addon command seems to be slightly different.

Does anyone have experience doing something slimier to this?
