TBF, you didn't say anything about reprising favorite modules (nor wanting to economize by recycling modules), but, rather: Which sounded like, y'know, if you just want to pick something up, you're talking the company that's famed for putting out APs. There should be somethings for you to pick up & run. You shouldn't /need/ to mine other systems for good scenarios.
But, I get it if you'd want to reprise an old favorite, I've done that with 4e/E and 5e pretty easily (not /my/ favorites, full disclosure: I didn't much care for modules back in the day, but 'old favorites' by general acclaim - point is, not hard to convert from older D&D to 4e or 5e).
If running Village of Homlett or Forge of Fury or anything in-between for the nth time in yet another new edition is something you're wanting out of PF2, anyway...
