I would strongly suggest looking at the SRecord utilities. They come 
with WinAVR but can also be found on Sourceforge separately. The SRecord 
utilities can be used to directly manipulate "load" files in many 
different formats including, obviously, Motorola S-Record, and also 
Intel Hex. IIRC there should be a way to do what you want through a 
series of calls to these utilities, which you can set up in a batch file 
or shell script. See the SRecord user manual for more information.
