Okay, I like what you're doing here. Can I see some variation on the lettering along with dropping the blue and green split circle and go with all one color? Font examples I like (from Word 2007) would include: Papyrus, Mongolian Baiti, Nyala, and Tempus Sans ITC.
and one with Tempus Sans ITC, I've bolded up the typeface a little. I don't own the other fonts that you suggested, they are microsoft fonts and I can't seem to get them.
