First of all, Sacred Gears aren't powerful enough of such stunts, only the Longinus. Longinus are the highest level of Sacred Gears, they are designated to kill God and beings equivalent to them like Lucifer or Beelzebub, so yes Longinus wielder can gain enough power to defeat even more powerful being with experience, training etc.

''' Second, the Boosted Gear isn't equivalent to the Heavenly Dragon. The Boosted Gear just has access to Ddraig's abilities, not power. '''
