If disk space is in short supply, you may be able to use unionfs of a directory on disk backed by a loop device mount of the ISO image.  This should use disk only for the changes.

Caveat: I have never used unionfs personally, except with Knoppix and DSL.

You will probably encounter difficulty if you exceed the original total image
size, however.  I've experienced this.  I had to delete other things I
thought were unnecessary before I could add files.  I ended up going with
remastering from an on-disk copy (as Sean said).  Much simpler when you are
increasing the total size.
