Geant4 does not, cannot, calculate the electromagnetic interactions between particles. So, you cannot expect G4 to simulate the beam-beam interactions.

Either way, particles can only interact with 'external fields' which the user has to define. You can build into your field definition some time dependence, and you can give each of your primary particles a relative time to each other.
