Absolutely.
I have an "Application Page" that is external to the forum files, it requires the main.inc.php page, grabs data off the Application page, and drops it in my specified format into an "Administration" forum that only certain people can see.
When you go into the forum, it appears as a new post.
So aye, quite doable and rather easy. You could have a cron job run that grabs the report, uploads it to a directory you specify with a given name, and then takes that name and inputs it into the {image} tags in a new post.
That way when a user who has access to that forum checks, a new post is there displaying the image of the report.
Or however you want to set it up
