Maybe Nora Geo instead of Neo Geo.
....or a modified version of the Neo Geo Station logo.
....or borrow from one of the newer, more colorful SNK candy cabs, like the Neo 29. (although I'm not sure that works with the CP)
....or a standard marquee in purple with her picture in the "now featuring" window.
You could try to incorporate the faces, but make them cuter.
Just throwing ideas out there.
Just had another thought: cute little bust-a-move dinosaurs....
