Will the new Republican congress investigate this?
Apparently it’s not out of the question. Here’s the Republican congressman from Utah on investigating the Bush torture regime:

CHAFFETZ: Well, it may be on the list as well. I’m not afraid of going after the Bush administration. I wasn’t brought here by the establishment. When I ran for congressman in 2008, I’m just a freshman year, George W. Bush, Orrin Hatch, and Bob Bennett, three Republicans, they campaigned against me. So I don’t mind going back and looking at ‘em. So I don’t have any hestitation whatsoever.

Will any other Republicans follow him? He’s on the Oversight Committee.
