This is a pretty hard question to respond to. It reminds me of an old Chevrolet car. The car was called the Chevy Nova, and they tried to sell it internationally under that name.
Unfortunately, in Spanish speaking countries, the car’s name literally meant ‘No-Go’, which damaged the branding.
That’s why companies such as Toyota try to make up words (one reason is it’s easier to copyright a word that didn’t exist before, and the other is you never need to worry about the translation).
I think your best bet is to try for an original word, or a modification of a word that sounds cool. Make sure there isn’t any lingual issues in Cantonese and run with it. Also, make sure the English word doesn’t have any stereotypical consonant sounds that people from that region have difficulty to pronounce.
Take Diplo for example. It’s basically it’s own word, but it’s short for Diplodocus (a type of dinosaur).
