For concreteness, the Harnoncourt recording I had in mind is this one: https://www.youtube.com/playlist?list=PLyXewGfDx5l0xsWKwAlHTT9P_elygrNF2 https://www.youtube.com/playlist?list=PLyXewGfDx5l0xsWKwAlHT.... According to the calculator at https://ytplaylist-len.herokuapp.com/ https://ytplaylist-len.herokuapp.com/ this has a total length of 147 minutes. At 1.25x speed it would be 118 minutes. I only did a very quick check, but playing it at 1.25x speed does sound comparable to other recordings I've heard. So I'm sure it's doable and would sound okay-ish. I know I have at least once heard a full (uncut) version on the radio that fit exactly into a 2 hour slot. Needless to say, I found it too fast. But it's true that I can't point you to a specific two-hour recording right now.
