I'm sorry to hear that your original name was taken.
I fear the same for my potential name.
I choose the first two choices on your poll. High Voltage sounds fierce!
And I actually liked blue moon until somebody pointed out the beer. I'm not a beer drinker either and didn't realize. Hahaha
I don't think you would get sued for using the name if you did. I'm sure lots of things are named 'blue moon' since it's a fairly common saying... And you would be fine as long as their logo and font isn't used.
