This sounds like an excellent project. I really want to test my understanding of Rev 13 - and you have added a lot by forcing me to look at how the RCC fits in. It seems likely that Revelation has elements from all four major interpretive schools - which is why each school is able to exist in the first place!
I think the confusion is largely caused by the individual schools excluding the others. The Preterists have erred by forcing everything into the first century and so blinding themselves to the later historical fulfillment of some of the prophecies. Likewise, the Historicists, in their battle against the Preterists, have blinded themselves to any and all first century fulfillments! I think this mix of a Preterist first century fulfillment of the first beast in Nero followed by the Historicist understanding of the second beast as the medieval RCC may well be the "real deal" that is revealed in Rev 13. This interpretation causes lots of bells to ring.
One nuance - I would think first century imperial Rome is the first beast, with Nero its representative, since it was much more than one man as seen in its seven heads and ten horns.
If the harlot is apostate Jerusalem, and the ten horns represent imperial Rome, then this fits perfectly with the judgment on Jerusalem in 70 AD. On the other hand, if the harlot is Rome, how is it that the emperors make her desolate? This view also fits with the harlot being drunk on "the blood of prophets, and of saints, and of all that were slain upon the earth" (Rev 18:24). And a 70 AD fulfillment of this judgment on Jerusalem literally fulfills the words of Christ and the time marker he used:Revelation 17:16 And the ten horns which thou sawest upon the beast, these shall hate the whore, and shall make her desolate and naked, and shall eat her flesh, and burn her with fire.
It seems to me that this is a powerful confirmation of this interpretation. And it is confirmed again by the judgment of the harlot which is a quote from God's judgment on apostate Jerusalem in 586 BC:Matthew 23:35-36 That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar. 36 Verily I say unto you, All these things shall come upon this generation.
Thus God declared exactly the same judgment on Jerusalem both times He destroyed the City and the Temple in 586 BC and 70 AD.Revelation 18:23 And the light of a candle shall shine no more at all in thee; and the voice of the bridegroom and of the bride shall be heard no more at all in thee: for thy merchants were the great men of the earth; for by thy sorceries were all nations deceived.
Jeremiah 7:34 Then will I cause to cease from the cities of Judah, and from the streets of Jerusalem, the voice of mirth, and the voice of gladness, the voice of the bridegroom, and the voice of the bride: for the land shall be desolate.
You have made a leap here from Rev 13 to Rev 16 where the "false prophet" first appears. But that's ok because the correlation seems clear:
Revelation 16:13 And I saw three unclean spirits like frogs come out of the mouth of the dragon (Satan), and out of the mouth of the beast (First beast Rome), and out of the mouth of the false prophet (Second beast).
