My idea is a balcony on the town hall that can be filled with minions to shoot down on attackers. The feat is introduced on TH 7. Minions you have trained can be placed in the town hall to shoot at enemies. The capacity of minions available increases as your town hall is upgraded:
TH7- 5 minion capacity
TH8- 7 minion capacity
TH9- 9 minion capacity
TH10- 10 minion capacity
The minions are not viewed as a defense and die with the town hall.
Hope you like the idea. Please vote.
