I think you should try it. I think an hour is appropriate for a lot of the story beats if you have a decent memory, though maybe an hour and a half would be better suited to some of the more involved parts. A lot of this is affected by your reading speed. There's a lot of reading.
For what it's worth, I also played it in bursts, but probably something like 2 hr sessions. There's a lot of rough, serious material in that game and I found it a lot to process at once, so I took breaks between sessions fairly often.
