You aint gunna find many people sympathetic to 5e here, for better or worse. You can ask for suggestions on certain things, but this is a forum for people who play an remade edition of dnd that were very reticent to move onto a simplified dnd system. I would be surprised if you found another person here who enjoyed 5e let alone thought about converting an AP to it instead of just playing pf1e here. Just my honest 2cp.
You could try a 5e reddit group likely with much better success though.
