It would be relatively easy to extend this script to unpack and pack the whole RKFW/RKAF file. This would remove our dependence on imgrepackrk and remove additional reads of the entire data for MD5/CRC purposes.
It might even be possible to attach a loop device directly to the system part of the file and do our modifications in-place is we can generate the offsets.
The script should get an option to copy it's input and name the modified output file
