Sounds good. As long as you're communicating from someone on the WordPress.org side of things, you should be good.

The thing I see is that you're distributing the icons under the GPL on WordPress.org, so someone could use those icons packaged within the plugin under the GPL with all the freedoms that it entails. The CC-BY-SA license seems rather useless to me if I can go get the same icons under a license with more freedoms. I may be missing something though.
