I just finished an 80 min project that was almost entirely made up of 4000×4000 stills… with complex moves and sometimes 5 layers (all stills). After much deliberation I ended up using Stage Tools Moving Picture Producer (with FCPHD 4.5 ram HUGE 800 U320r). I tried it first as a plug-in, but with the high res stills, it proved unusable as it brought my system down to a slow crawl. Producer looks just like the plug-in however it is a stand-alone application. I would create my moves and then export a QT movie to FCP, which would then allow me to further tweak the look (color correction, filters etc.) without bogging down the system memory cache when working directly with a still. The one flaw is that there is no way to import a scratch audio track for timing in Moving Picture Producer (windows version allows this). So if timing is critical, one has to flip between FCP and MPP and take accurate timecode notes (MMP utilizes timecode). The time it took to render out a QT movie (10 bit uncompressed corresponds almost directly with the length of the movie so 2 mins length = 2 mins render roughly) and then importing into FCP was miniscule compared to rendering out the same move within the plug-in version of FCP.
