You will probably need to modify the example code in two ways. First, to allow the /mydet/readFile command during the "Idle" state; it is presently restricted to the "PreInit" state. The "Idle" state is what the UI comes back to after /run/beamOn completes.
Second, as you already described, you'll need to modify the code which reads the GDML to do a full geometry clean out before reading the new file. This should be handled by the detector-construction class, before calling the GDML reader.
