KMB x Genshin Impact collab bus concept

I got this idea when I was browsing on the internet and discovered that the popular video game Genshin Impact has done many collabs in mainland China, including one with Cadillac which produced 6 cars decked out with the livery from the in-game characters. So I was thinking, what if I take that concept and apply it to the buses of Kowloon Motor Bus (KMB), the largest bus operator in Hong Kong and Asia?
