Not that these problems are impossible to solve, but they are nontrivial in practice, I'm afraid. It would take quite some effort to turn the fantasy into a reliable theory, and then quite some more, into a practical swarm.
Will be cool though.
What would be even more fun (i.e. stretching the limits) would be to include a 30-300 mhz radar in the mix, which would resolve just fine with dispersed nodes, and penetrate most stealth coatings and bounce off the airframes of the enemy.
