You can easily (and sparsely) set the minimum size of the regular output 
file with a command like this:

  ddrescue --sparse --input-position=<isize-1> --max-size=1 infile 
outfile logfile


About making the size calculation automatically I have still to think 
how should it interact with other options, for example with 
"--domain-logfile".


Best regards,
Antonio.
