Potentially, yes.

Whilst most top sprinters of the current era have been built like the proverbial brick out-house, there is no perfect size and Caleb Ewan is tiny. Cavendish is not as powerful as some of the top sprinters, but he sprints with a low head, flat-back style which is very aerodynamic. He's also fairly narrow across the shoulders (for a sprinter)
