Changing site URL

As we are facing a drastic change in the name of our small association, we are bound to change our site URL, too. Here are few suggestions, in the next few weeks, one of these (or any other better option) should become the new adress:
1) micron-d.blogspot.com
2) md.blogspot.com
3) micron-sd.blogspot.com
4) msd.blogspot.com
5) mdev.blosspot.com
6) www.blogger.com/micron ...
etc.
If you have any other better ideas, we will welcome them!
