Ziggs satchel charge tower demolish idea

It would be cool the when Ziggs chucked a charge on the low health towers that it would stick flat on to the tower, and that when the charge exploded, it would blast rubble from the tower back, knocking back units and dealing a small amount of damage in a small radius. Think mini sindra knock-back attached to the bomb/tower interaction. Just think it would be interesting and thematic, seeing as how brittle towers look when low hp, that a satchel charge would blow the tower away.
