Sure. The dat fields are just pointers to objects: you can do anything
you like with them.

Bad idea. The datafile routines are in charge of allocating and freeing
memory: you shouldn't go anywhere near this yourself. You've just 
copied the address of the sprite objects, not the object itself, so
you don't own it and should try to destroy it. Use unload_datafile()
when you want to free up the memory. Actually, I'm surprised that
it doesn't crash when you reach this code!
