It's a problem I had several times too, and I use Warp's way, doing it 
in an animation.

The only problem I couldn't solve like this is when I want to use a 
previously rendered image as a height field and I want the height field 
image to use the hf_gray_16 option, even though this option appears in 
the script and can be conditioned it seems that it is handled just like 
any other output option by POV-Ray so that all images are rendered with 
the hf_gray_16.

Beeing able to change options dynamically would ease things up a lot,

For the accessing part, you can access parameters like resolution, but 
not all parameters are accessible,
