He is absolutely adorable and I'm sure we all understand that you're not trying to replace Cirrus. Some cats just have "issues" and it sounds like newbie kitty won't be one of them.

I really like QSA suggestion of Zephyr. He would be the oppositie of Storm:

Storm: Gray and big
Zephyr: Light and small

Congratulations and I can't wait for you to bring him home! It's been sooo long since you've had a kitten in the house that I'm sure you will have many tails to tell.
