My suggestion would be to wait until next MegaPOV (which will come after 
POV-Ray 3.6).

Some additional notes:

- floating point binary output is somewhat critical in terms of 
portability so it would not be a good idea to make it the only available 
format.
- some of the manipulations you mention could better be done internally 
in POV - this would avoid introducing new proprietary file formats and 
and specialized programs.  Next MegaPOV will contain a new post 
processing feature for this as well.
