Yes. Just remember to replace every instance of fd with mnt.

I should have said "add files to the DOS filesystem on the zip disk".

You can go from large to small. If you have resize2fs, it's even
easier:

resize2fs fs.img new_size_in_blocks_goes_here

A block is usually 1 kilobyte.
You then need to trim off the end with dd:

dd if=fs.img of=newfs.img bs=1k count=new_size
