I love the name, but I prefer
Baltasar and
Baltazar. The H looks superfluous to me. While I don't at all like
Sebastian, I agree that they'd sound nice together.
Some suggestions:
Baltazar AshBaltazar GeorgeBaltazar ChristianBaltazar PhilipBaltazar EdmundBaltazar ThomasBaltazar EdwinBaltazar HaroldBaltazar CharlesBaltazar MartinBaltazar LyleBaltazar Eric
I like the idea of grounding it with a traditional middle name, but I'm not really sure what sorts of names you like, heh. I don't have any really good suggestions for middle names just now.

"Yeah. It's Latin for 'kick me'."
