There is the kernel of a good idea here. I don't think it need be even as complicated as you have made it however. Many monks already add Update text when they make a significant edit. A way of facilitating this, already common practice, is all that is needed.
I'd suggest (as you do) an extra text input field to capture the update text and that that text be appended to the end of the node text with "Update:" prepended in bold and perhaps the whole lot wrapped in small tags.
That is a fairly light weight change and doesn't require new DB tables or other extra stuff added to track update history.
