I don't see how "hu"may be perceived as exclusive. It is inclusive, as "HUman"
is inclusive of both men and women.

"Hu," indeed, is omophonic with the name Hugh.
I don't think, however, there will be much confusion about it: Hugh
occurs only once in 1666 males; the name's popularity rank in
the U.S. is #254. Even more popular proper names are safe
from confusing with their common name doubles. Nobody confuses Ann with the
article "an", or Nick with a small cut, or Rick with a stack
of hay.
