Revolution in its real sense is not possible to eventuate in Pakistan. The reason is very simple, first of all we do not have a uniform society and culture all around the country, and second, our society is still not industrialized enough and in a serflike society, revolution can only take place when big land owners or nobility or aristocrates (whatever you call them) are convinced enough to bring it about (like in French Revolution).
Other thing I feel, no revolution will bring any change in Pakistan, because any revolution for the time being will only serve to topple an incumbent government, still the deep rooted difference among the different segments of nation will prevail. Revolution means only Revolt against rulers, nothing else. Our nation is still struggling to unite under a common ideology, and it is pretty much evident that the actual Ideology of Pakistan has lost its essence among the masses. The condition of Pakistan will only improve in a long run, and that also only if the right path is followed throughout. Otherwise no ad-hoc solutions like revolution is gonna work effectively.
This is my personal observation
