About the whole theory, I mean, it's nice and all but there are some things to consider. For one, after the incident at the Ocean Palace and all that, you never see Schala again, right? To get a clone, wouldn't you need the original person to see (ahh I can't spell his name, the face and hands dude at the fair in that tent where you get the clone of Crono from) whoever to get the clone from?
But let's say that you do manage to get yourself a clone, you could actually do this after destroying the Black Omen and doing all of those quests and shit, but before actually beating Lavos. The reason why I say you should do everything, including the destruction of the Black Omen but not Lavos is because; one, Schala also became one with the Black Omen or something or another...I think, and the other obvious reason is because as long as Lavos is alive in 1999 A.D. to cause the Apocalypse, you'll have a bleak Future to go to and a Death Peak to go to, to do the whole Time Egg/Clone switchy/Revive/Thingy.
Now, when all you have to do is beat Lavos, and you have yourself the clone, however you managed to pull this all off, let us continue. Go to the End of Time and consult with Gaspar, and you'll all talk, yada yada yada, you know the drill. If Gaspar can make Chrono Trigger/Time Egg, he can definately make another one with the same effects. So, however long it takes, and when you finally have yourself the the Chrono Trigger/Time Egg, take the Epoch and go to the Future so you can go to Death Peak.
Now, with business taken care of, you would need a certain point in which to go to, so you can freeze that moment and make the switch with Schala's real body and the clone of Schala, and it all has to fit in accordingly so as to not mess up the Space Time Continuum Theory or whatever it's called and not to cause any possible paradoxes. A good time would be after Schala teleports the remainder of Crono's party and Magus to a safe place, but before anything else major happens. With this moment frozen, make the switch, and get the hell out of there.
No before you try and contradict this, let me explain some more stuff out. How could this happen if Schala supposedly becomes part of the Black Omen or whatever? Well, quite simple, the clone of Schala would go and become part of it or whatever or be sent to wherever the real Schala was intended to be sent. Nobody would know what happened because nobody would witness Schala out of no where, becoming some stiff clone of herself. And besides, the Black Omen gets destroyed and Queen Zeal was too busy with immortality and ultimate power to care what was going on with the remains of the Ocean Palace, during and after the Ocean Palace incident.
Now, back at Death Peak, Schala is back. Return to the End of Time, have your little get together reunion and all, and go beat Lavos since that would be the last task to do. Once Lavos is defeated, the world is at peace, and Belthasar, in the peaceful Future, would discover the Frozen Flame but Schala would have nothing to do with it since she was saved..unless her fake clone was intigrated with the Frozen Flame..or something. Well, now needing no project to free Schala, since she would technically be free, there's no Time Crash, and the future can continue on as it is.
If there's anything wrong with this, don't be surprised, because I expect there to be HUGE mistakes in this, but it was something I had just came up with and thought I'd share it for the topic at hand.
BTW: Why in the hell would you call somebody a "newb" just because they are sharing a possible theory with the Compendium? I don't see the logic...who cares if the theory is crazy or whatever you want to call it? Oh, so now we can't post off the wall theories for fun without somebody judging us by calling us a "newb" to try and make us feel stupid?? Wow, you must feel really cool now. Well, whatever. There's my two cents.
