comment Why do covalent bonds form?
Actually the classic reference to learn all this is Ruedenberg's Rev. of Modern Physics 34,326 (1962), but you can get nice pedagogical presentations for free (e.g. google "Rioux why covalent bonds form"). You got the role of kinetic and potential energy reversed. Because of the virial theorem, the decrease of potential energy wins over the increase of kinetic energy: the bonding orbital is contracted except at the bonding coordinate, where is expanded; thus the gain in kinetic energy is not excessive. This guarantees minimization of the total (kinetic+potential) energy.

comment supressing certain decay paths and enhancing others with interference
There is already a vast literature dealing with the coherent control of scattering processes, particularly in unimolecular reactions. The area is called Quantum control. See for instance the publications by Paul Brumer and Moshe Shapiro. There is also a lot of work in the control of quantum tunnelling processes and decay processes (see for instance the work of Kurizki). I am not aware of any work in the control of the production of antimatter.
