I suspect it depends strongly on what you will do with the extra time. I started consulting, which would have been impossible at just one day per week, but it is totally legitimate to use it for non-revenue pursuits and going “one step at a time“ (going 80 -> 60 would likely be much easier) could make sense in that case. Another consideration is whether you would lose benefits under a certain threshold. I almost guarantee that HR will not know off the top of their heads, so before spinning your wheels, on fuzzy lifestyle questions you should start the process of getting official documentation on how things like healthcare and vacation days will be handled, it might make the decision a no-brainer.
