Since it's bad practice to modify drupal_build_css_cache
directly ,
does drupal allow overriding this function somehow?

no, it is not: there is only one call to drupal_build_css_cache()
from other Drupal code, and there is nothing "dynamic" there to make that call overrideable.
why do you want to modify drupal_build_css_cache()
? what are you trying to achieve? if it is something others might find useful, you might suggest your idea to the Drupal project and try getting it included into core.
