Doubtful, since the creation of Sub-Species Balance Breakers are the result of a Sacred Gear's host gearing themselves - and their desires - in a certain direction. In the case of Kiba and Jeanne's Balance Breakers for Blade Blacksmith, they were probably influenced - or even inspired - by Dragons. But as to whether or not they would make their hosts vulnerable to weapons such as Gram or Ascalon, I don't think so. Especially with Kiba as his Balance Breaker is technically a customized version of the "original" Balance Breaker for Blade Blacksmith, Blade Knight Mass.
