Can you think of any blog names...?

I suggest lunainspace would be suitable...actually what is your blog about? Just create a domain name that describes your blog so that it is useful in ranking, you can try to get a short and one that is catchy,easy to remember.I further suggest instead of a secondary blog name like abc.blogspot.com it is wiser to have your own domain name like lunainspace.com so that you will have to your own personal domain name, you can host it with much more features like add extra plugins, and sell it whenever you want to...Providers like 9cubehosting.com offer domain name at low cost along with economical freebies.
