I'm not sure what she would look like. But Hana-chan is already cute on her own, so... :3 ?
Plus, I have a feeling that if all the Taiko characters had Taiko versions of themselves, some would look VERY ALIKE, particularly Hana-chan and Kodama (Wii2), and then Botan and Kodama (Wii1) which would only differ in hairstyles hahahaha. I am curious as to seeing how ugly Waruru-don and Dokon-don will turn out to be though, ahahahaha~ Wait, that gave me an idea...
ARUMI-DON(ko?) PLZ, NAO! Also, Teruru-don.
Actually I have a wide imagination, but not yet enough to imagine what Taiko versions of anyone would look like... :/ lol.
EDIT: How about... Saitama-don *is shot*
