@CongoJack:
I get what you are saying and if / when it comes like you predicted, I won't have any problem with that. Again, not sold on my own theory, not promoting it, just saying 'I had a thought and it goes a little sum' like this'. One last thing - should they manage to get back to where they came from ( through whatever reason ), of course something would change. They could tell the then-shogun that in 20 years his country will be free again if he dies now - as the time traveler's can report to have set all the wheels in motion to end the reign of the new shogun. And we readers could see the shogun go out with a smile on his face knowing that the whole ordeal would just be an intermezzo of 20 years. Who knows how often that time fruit may have sent Kinemon 20 years in the future already, having him try to get Wano back for Momo and coming back to 20 years ago if the plan does not work, only to get send again? I certainly do not.And yeah, that 20 year old picture I spoke of would mean that they are, after seeing the timeline where it all works out for Wano, delivering themselves to their enemy - and they would now be dead. Prototypical Oda writing style - life goal achieved, die with smile.The ending would still be 'happy' as Wano will be free, but it will not be costless / cheap - victories should and do demand sacrifices, as has been established in the context of the series many times by now. On the other hand, Momo would have to stay in the future no matter what, wouldn't he? So that Wano has a shogun after the Wano arc. Let me think about all of that some more :)
Who knows. It could be whatever Oda wants, but it would feel quite strange to me that he plays the two ways time travel card.I think that the time travel fruit just sends you to the future. Maybe based on your needs, as Kuma sent the Strawhats to the place they needed to be, the best place for them, some fixed years, some stated years…. And as we have seen Kuma sending people away but never bringing anybody from a far away place (it repels things, doesn’t it), it don’t think anybody is traveling back in time.But again, who knows.

@Thatanas:
My thoughts are that you should stopw ith the idiotic perv comments. Jesus.
They are perv, as many Oda’s jokes, but I don’t think they are idiotic.
