Celestial Reloaded does have a right sidebar page template for WooCommerce…but as you mentioned, a need for a dedicated theme for WooCommerce might be something I will consider. I’ve been pondering this for a couple of months now and it very well could happen very soon. I’ve had enough people ask me about WooCommerce in my themes, so it very well could be a reality….although it might take me a couple months.
It’s interesting that you mentioned about the curved design style for the header showcase…when I created Celestial over a year ago, I didn’t expect this theme to be so popular. It turns out a lot of people like that curve for some reason. I’m planning to re-code the Celestial theme soon, including a lot of design/style enhancements. Perhaps I could make it more WooCommerce based as a full shop theme option.
