This actually reminds me of Firefox's live bookmarks and the forgotten add-on called Brief. Have you used it? Brief basically wraps a GUI and some features around FF's Live Bookmarks. The live bookmarks have no feature other than the read item gets an un-bold. Assuming your hack provides little more than the basic feature set for feed reading, otherwise, the combination of bookmarks and feed reading is not much promising.
