Although you could, I don't see a need to alter the actual hlp files. Perhaps by putting a link at the end of each topic/item to its forum topic would be all thats called for if it is altered.
The forum topics really only need usage and a description on its intended use. ie $scid(N)[.id]
The downfall to this suggestion is that this particular forum would need to be moderated to keep the replies on topic.
To keep down on the moderating, perhaps limit access to registered users(mirc registration). But again that would require a little more work as well.
