Although it would be cool, I seriously doubt we'll see Scott Bakula in the movie. There may be some more Enterprise references, though. There are a few in the Star Trek Ongoing between-movies comics.
I pictured Archer as a semi-retired old teacher. At 140, he'd be about the same age Admiral McCoy was in "Encounter at Farpoint" - if he hadn't skipped a few decades using time travel. Which he was something of an expert in!
As for T'Pol... I have no idea. She did become something of a born-again Vulcan in season four, so she may have been there in 2258
