...that would have been a great title (and cover photograph) for a 1960s acid rock hippie band.
That aside, the crew of martial artists that Prince Kublai hired during ROCH was one of the most multicultural groups in the history of wuxia. It featured an ethnic Mongolian (in previous editions, Tibetan) in the Golden Wheel Monk, a Persian in Wan Hak Sai, a Miao in Siu Seung Tze, and an Indian in Lui Mor Singh. Not sure what ethnicity Ma Gorn Jor belonged to (his surname suggests that he's a Han, but he might be a Uighur), but Yeung Gor (who briefly joined this unmerry band) was definitely a Han.
If I were Jin Yong, I would have added a few more guys to represent an additional few additional ethnicities: a Cossack or White Russian, an Arab, and perhaps a Zulu (though that would be stretching it because the Mongol Empire never reached Africa).
