You would have to use different logical volumes for spheres of different dimensions... and
may want to exploit the concept of G4MultiFunctionalDetector.
The alternative can be to still use parameterisations, but make such that you pre-generate
the random indexes for each event to be used in your parameterisation (instead of randomly
generating them directly in the parameterisation functions), notifying the run-manager that
the geometry changes at the beginning of each event.
