For me, DHS could definitely be a half day. I'm a Star Wars fan too and basically spent my morning doing the following on a CL 6 day: TSMM (RD), ToT (FP), RnR (FP), Launch Bay (we did two character meets - Kylo Ren and Chewie - and skipped the movie portion. Probably spent 30 minutes. We did not spend loads of time looking around but did take a quick look around), Star Tours (FP). We were at lunch at the Brown Derby by 12.
Downfall of spending the morning at DHS and doing evening at AK is missing the Star Wars fireworks show. I did not see it because we only had one day and decided to watch F! - so can't comment on it's level of awesome-ness.
For AK, if you wanted to do it as a half day in the morning and your absolute priority is Pandora, you won't have any trouble getting the rides in. I'd plan to RD FOP and FP NRJ. If you can get a FP for KS and EE, then you can definitely get all of that in even if you do end up with a 30 minute wait for FOP at RD. Downfall of doing AK first is not seeing Pandora at night.
So I guess it's really up to what your party is prioritizing.
Not sure if it's still happening (haven't been on the app recently to see if people are still reporting it) but AK was opening early. Basically people (myself included) were arriving at 7AM prepared to wait for an 8AM opening but instead walking into the park getting on the Pandora rides. If that is still the case for your trip, you're home free. I was on and off both of the Pandora rides by 8:15, and I arrived at 7:15 that day - walked straight to NRJ and rode. Then got out and walked over to FOP, waiting 20-30 minutes tops.
