Deceptively simple.
For one, you have to sort out liability for checked valuables between check-in and return-to-pax - because currently neither airline nor handling agents nor pax's insurers will accept it. Or you ask pax to accept liability for your own systems being so prone to loss/theft that the risk is uninsurable...
For two, you need to work out what to do about pax with life-essential medication and/or medical equipment. Currently such pax are advised (by various official sources) that this stuff _must_ be in cabin baggage (with backups in checked baggage). I know this because, as of 18months ago, I am such a pax, and if/when I do fly again I will have to consider how to handle this.
There's a bunch of other issues that I can think of without even trying, but the big one from an economics point of view is that you have to remove all non-food/drink air-side shops (which is actually fine by me, but you'll need to work out which airports/airlines will still be economic).
