If you want to convert between class references by means of 
pointer repainting, you can do so by casting to void* in between.

As a side note, you might want to revisit your OOP terminology – 
in both this and the dm.D.learn thread, you are referring to 
down/upcasting in the reverse sense compared to the common 
definition.
