Sure,
After you make your iso, look in the first bit of it where the TOC is at or just do a search for the name of the file you're wanting to edit. Once you find it, look just before it and you'll see the size listed in Big Endian/Little Endian back to back. For example: This file was supposed to be 805,306,368 bytes (3000000 hex) so it needed to show as "0000 0030 3000 0000" (byte flipped) in the ISO. Say you had replaced the file with one of only 16 bytes... It would say "1000 0000 0000 0010". You would replace this with the size you wanted the file to say.
Need to know how to convert the size from bytes to hex? Just use your calculator (right in windows) with the scientific option, and enter the size you want the file to be (decimal), then click the HEX option and you'll have the size in hex. Now just byte flip it and there you go.
Again, thanks goes to Darkfalz for pointing me in this direction.
