Mountable Town Hall.
In my opinion the TH roof looks well suited to house other defences/storages.
The square shape makes it perfect for the clan castle (clan castle could change to suit colours of TH and blend in)
benefits being both TH and CC could both be centralised.
The roof could be a universal point for everything. Xbows, mortars, DE storage etc etc.....
The benefit being that the hit points of the TH and whatever you've chosen get combined increasing your TH's hitpoints.
👍👊
