A good character designer should have no problems designing characters with a wide range of physiques. For example, Yoshikazu Yasuhiko did this for Gundam.
He may have started with a stock template, but see how he varies everything to create multiple types of character? And this is from a show from over 30 years ago. You can see similar things with the Macross cast or as a more recent example, try Eureka 7.
also space aids is GHINIUS from 08th MS Team
