Have you tried proving to a non-SDA how the first four trumpets symbolize the fall of Western Rome? I believe and have faith in our historical interpretation, but I must admit that nothing else seems more contrived and more forced to fit. It is so unnatural.
In this same way I believe we can "force" the last half of the 6th seal and the 7th seal to fit in 1844. The difference in timing is not a problem for me. The similarities are close enough to warrant comparison.
When John was told to prophesy again without repeating the time portions (Rev 10:6,11) I believe we have all the justification we need to reapply the seals and the trumpets - indeed, I believe it's our mandate, our obligation....
I think MM, your reading of Rev 10 where John is told to prophecy again is sound. If a revival among Adventists hinges to a large part on understanding the books of Daniel and Revelation better as Ellen White has said, we can expect to receive new insights into the prophecies. It seems likely to me that one of the main passages that is behind Ellen White's prophecy that the study of Daniel and Revelation will bring revival is this text - in other words she very likely understood this text as predicting the same revival that she spoke of.
PS, I haven't been active here for several weeks. I'm not able to participate much now or in the near future but let's keep praying for each other. And for those who are able to participate more than I can right now, here's a promise for you all:
3:16 Then they that feared the LORD spake often one to another: and the LORD hearkened, and heard [it], and a book of remembrance was written before him for them that feared the LORD, and that thought upon his name.
3:17 And they shall be mine, saith the LORD of hosts, in that day when I make up my jewels; and I will spare them, as a man spareth his own son that serveth him.
3:18 Then shall ye return, and discern between the righteous and the wicked, between him that serveth God and him that serveth him not. Malachi
