What is his registered name? I always really like to go with a horse's registered name - if he ends up with someone elsee, his lifetime achievement scores will be unresearchable if the new name is lost - I don't know, its just how I feel about it.
But, if you really want to find a new name for him, can we start by knowing his registered name? Might help.
I can't see the OP - did you say what color he is? Must visualize....
Airborne? Oh. Yes, he can take a joke. Once. After that, the joke's on you.
