Hence the requirement of "decent editor". As a direct example, vim -b.
It won't modify the file size unless you specify to change the file
size. Get in, find the MAC, use R to modify the bytes you don't like.
With the GUID, the idea isn't to remove it as much as either put in
bogus data, or a mess of zeros, or something like that -- overwriting
the bytes directly.
Unless MS has changed their file formats, they didn't bother with a
checksum over this data.
