Actually, Kepler's played 20% of his career games in CF so I'd say he's done more than just fill in in a pinch. If one of Celestino or Gordon would get the right return, I'd be just fine with Kepler in CF when Buxton's not and Kirilloff in RF, especially with Sano nearing a return and a lot of talk about being in the running to get Josh Bell's bat down the stretch. Contending teams can never have too many bats or arms.
