Just remake it as part of the show and save the prequel era that way. The Clone Wars explores the themes the prequels were trying to significantly better, even if it doesn't explore all of them as much as I'd like.
I am not so sure though. Take the trailer scene for example, with Mace Windu revealing he's sensing a plot to destroy the Jedi. In the movie, he revealed it only to other council members: Yoda, Ki-Adi Mundi and Aayla Secura, just after Anakin left the meeting. So he only talked with the most trusted people about this in a very discrete setting.
In the trailer scene, it looks like he is talking about it in a meeting that also includes Plo Koon, Depa Billaba, Caleb Dume and two clones(!!!!!!!!). So, apart from the fact that Caleb Dume as a mere padawan would certainly not be in on the council's most secretive talks about this kind of stuff, it's virtually impossible to talk about it when clone troopers are around. And all that re-interpretation just to work Filoni's OC, Kanaan, into the scene. I am not sure how this would be an improvement, as it undermindes the secrecy and discretion of the council members about their mistrust of Palpatine. So I think that possibly, that line of Windu does not actually belong to that scene like the trailer implies.
