Next timeline we wind up with is where Doc dies in a different way. Then where Marty's dad was never born. Then where the Tannens own the town. Then where First Citizen Brown rules with an iron fist. And then a few others that we might visit in the later parts. The story may end with one of our existing characters going back to before the whole debacle happened in order to set the speakeasy on fire and get the plot rolling in the first place.
Having said that... It might be that Doc really did start the fire. He knocked himself out so that there wouldn't be any witnesses. How else would the arsonist know where to find him?
Other possibilities for the arsonist: Marty. Einstein. The other Einstein. Hitler (why do time travellers always somehow wind up meeting him?). Carl Sagan. John F Kennedy, right before he assassinated himself. With time travel and stable time loops, anything is possible.

I can say I really like your theory, Flah! Why not? Actually, if your thinking works out in the end, my preferred scenario is the one in which Edna from some version of 1986 (from a point AFTER Marty's original time travel to 1931, of course) actually goes back in time with Marty and Doc to redeem herself by setting the speakeasy on fire, and actually inspire her younger self, thus becoming her own hero!!! Now THAT would be a twist, if you ask me!!!

The only problem is, how will Doc and Marty preserve the secret of time-travelling for themselves?... Hmmm... Guess a bump on the head should do it...

Also, in your theory, it makes sense that Doc's been gone that long in the original 1986, because it took a Delorean to finally reappear out of nowhere for Marty to figure out why, as he couldn't have guessed that himself after just a slight pause from Doc. (I think this one is just due to his sharpness.

Oh, and he'd just have to wait for the Delorean to appear, which wouldn't happen in another several months, and it'd probably blow his mind, so it's probably better for him to be this way.

) So, having said that, at the end of this adventure they could just return to 1986 BEFORE Doc's long pause, have a good incognito time somewhere, and wait for another (how many again?) months just to appear at the right time and claim Doc's possessions without damaging the time loop. The funny thing I'm trying to point out, Doc could've been well alive hidden somewhere in 1986 AND dead back in 1931 "at the same time"!!!

I hope that's as simple as preservation of time loops which are always complex and potentially broadly spanning through multiple partially parallel linear time portions (meaning, actually MADE of changes to linear time portions, as explained above), and stable enough if nothing TRULY radical happens, and if that's how time functions in BTTF universe, then everything should fit. On the other hand, does time function like that in real life??? That's what I'd really like to know...
Although, we can agree that BTTF pretty much successfully sums up the coolest aspects of both theories.
