effective against what?
What is the driving force behind such an idea? Concrete bombs are popular as they match the weight and shape of regular bombs precisely so you can use them for precise low collatoral damage attacks without having to change anything on the aircraft or the guidance package.
Sticking a bunch of redcued calibre training bombs into a cluster munition really ignores the precision issue and unless you want your cluster munition to have an inert option that matches the "live" submunitions in terms of size shape and weight (and thus aerodynaic profile) you would be much better off filling it with smaller steel/tungsten darts/flechettes:

On the second issue you have to define brainwashing for anyoen to really start to answer it. All military soruces have been exposed to some sort of effort to ensure they are motivated to fight for thier nation and desire to defeat the enemy. Sometiems it overt and targeted and other times its more subtle and about instilling a sense of honor and duty i.e. "i may not care about the reasons behind this war but i'll fight as i took an oath to serves" etc etc.
