You can, if the consuming system is format-aware. I think MSI can fall into that category. I developed something like this to put an md5 hash in a comment in the first line of a code module at a place I worked. It simply read the file, removed that line, and hashed the rest of the file data to generate the hash for comparison. This was just to stop programmers changing the code without submitting it to a secondary system for validation/tracking (easy to work around, but that shows intent to bypass policies when we see it in the repo).
