not without some scripting. since radius is not a per timestep
property. please have a look at this document. in section 5.4 there is
an example for changing the charge of particles (another global-only
property) dynamically in a trajectory. you could adapt this for
modifying the radius instead.

this has been used for visualizing results from eFF simulations with
LAMMPS in the past.
