Such screening at airports is a waste and will be a waste in the absence of revolutionary developments. Such work as you suggest is best done by intelligence and law enforcement agencies prior to a move on the airports. And even there intelligence agencies and secret police frequently focus on the wrong subjects despite days, weeks, months, years or even decades of observation. There is no reason to belive that a screener at an airport with 10 minutes to 10 hours of observation of even just one individual will be able to do any better job.
We can begin with better explosives detection equipment and processes and applying it in a more systematically meaningful way.
