Honestly, if you’re going to get up early to rope drop, I’d get there an hour early, RD FoP then do Na’vi. If you are there for FoP, you can get off then jump on Na’vi with little to no wait so long as you aren’t late and way back in the FoP line. I suggest this route for a couple reasons: 1. Na’vi isn’t really worth the effort of rope dropping (you can even get FPs pretty easily by refreshing) and 2. You’re almost certainly going to want to do FoP more than once. I was there in late November, got to AK at 8 for a 9 o’clock open, I was on FoP and off by 8:45. Walked over to Na’vi and waited zero minutes. Was in and off both basically as the parks “real” opening was happening. I had a later FP for FoP (around the time you mentioned) and did it as I left the park. The other beautiful thing about that approach is so many people go straight to Pandora even if they show up at 9 for a 9 o’clock opening that if you knock out both Pandora rides quickly, you can walk on to other stuff like Safari and EE. The day I’m talking about in November, I did FoP, Na’vi, KS, EE x 3, Dinosaur, Festival of the Lion King and then FoP again on the way out around noon.
