Do you see Roe v Wade being overturned in this timeline sometime during either Trump or Pence's administrations?
No. White women vote GOP and the deal was, if Roe is tossed, they go Democratic. Abortion is pretty much a sham. Everyone knows that the GOP uses abortion as a cultural codeword, not actually tossing Roe. They'll limit abortions some but a gutting of Roe would kung fu the RNC.
That's how Charlie Crist/John Boehner-style republicans see the issue, not Tea Party republicans.
I guarantee you that if a Tea Party socon been elected in the style of Walker/Rubio/Cruz, they absolutely would've gutted it. They're true believers, Pence would do it as well.
The only way Roe isn't gutted with the GOP in charge of the government is if the republican has some inherently moderate tendencies a la Jeb/Kasich/Christie/Trump, which is why your timeline wouldn't work if it features a Tea Party republican or a pro-Tea Party republican (like Pence) in charge of the government.
