As I understand it, you should be able to. But I’ve learned that the future of PyRevit is probably going to keep going forward with both P3 AND P2.
P3 will offer some more luxuries like (hopefully) pip packages and modern syntax
P2 will offer robustness and better performance. (Because apparently ironpython interfaces more efficiently with dotnet than P3)
So the choice is up to you, I thought I’d just provide a bit more nuance that could help you make a choice.
