I'm not sure but that's an innovative solution... if DSS plays ball - worth a try.
It might be easier to convert your raw files and create your masters with the script and drop them into DSS with no bias frames or master.
Regim, which is free software, will do all of this without manipulation, but I have found that getting the settings right is essential to success. If you go to the StarTools site there's a post in the discussion forum on image calibration with Regim which might help should you give it a go.
