I'm gonna be a killjoy and make a random prediction that the anime will have a third future timeline =P

But seriously anime team, if you want to add filler, add filler that actually bridges up the "story" properly like legit episodes of the alternate timelines(like you said) and maybe even what happened in the Dragons' time prior to seeing the Gate and coming through it. So many possibilities if you think about it.
