Yes, you have to be wary of what you need to retain but for the final
internet editions that are in greyscale/"black and white" a lot can be
dropped.
Technically speaking the PNG-8 files within the browser is never
likely to go much above a 72 dpi "Text Size" anyway. For the master
images obviously you'd retain more meta data. You can reintroduce some
values anyway. In either case the PNG-8 is scientifically superior at
compression than GIF.
You also have to ask what has been kept in the current GIF files and
by the looks of things not much.
