in that case you missed few things
SRK or amir khan is also needed, they make movie a blockbuster before it hits multiplexes and a sexy and useless bollywood actress, plus as you recommended 6 songs at least two of them sung by rahat fateh ali khan and atif aslam or kailash kher
or else
give it to hollywood
they will make mission impossible 4 or behind the enemy lines 4, though they can change name of locations.
and they dont need six songs
