Hmmm, haven't tried it, but you can use both GetLayoutObjectAttribute and Insert from URL can "Scrape" the HTML from a webside. This HTML can, in theory be set to a web viewer. If the HTML refers to other files, this won't work, but if it is just HTML, it might.
So I tried this out it works very good. I now trying to understand how to construct a scrip that can do this, after the HTML is confirmed to be loaded?
