If it's just a 50%+1 override then the mayor wouldn't in practice have any special powers. Veto threshold would need to be 60% or 2/3 or something.
He'd have the power to implement policy without Council approval, and all the politics involved in that. The point would be to streamline the process, allowing the mayor to "get things done" faster. Of course, anything the mayor approves will need de facto Council approval.
