If you mainly value the two Rolex for their market value, then definitely get rid of them now while prices are high - no point holding on to them otherwise in my book. Personally the AP does nothing for me, so that would be going too. On the PPs, there are perfectly valid complications amongst the Nautilus and Aquanaut ranges, but appreciate you sound set on the Complication range. The 5146 sub-dials put me off, but it's your preference that matters not mine. I'd say consolidate and go for a PP complication.
