I like your simplicity approach, but 800 film outside is just such a drag, even with the appropriate filters. It lacks punch, and if you're shooting in lots of light, do yourself the favor of a slower film.
Now, if you're doing black & white and can load up with RED & polarized filtration, that could be cool. At the least, I'd switch to 400. With a 1.4, you'll be hard pressed to need the 800 (although I do love portra 800 myself, and thus, totally understand its appeal).
