I shoot both the D800 and the K-3 together. Generally I use the Nikon for "wide" and I use the Pentax for "long". In particular, I absolutely love the DA* 60-250mm -- what a great lens. I did extensive testing of the K-3 + DA* 60-250mm versus Nikon D800 + AF-S 80-400mm VR and I could not see any IQ difference in 20"x30" prints. I happen to like a two-body kit so that I don't have to change lenses. Particularly for events. I don't find switching to be an issue. For RAW processing I use DxO Optics Pro on all my cameras so I have a common "look". The new v10 version is a big improvement. Additionally, all my cameras use the Arca quick-release system as well as OpTechUSA connectors so everything just "works" together, whether it is for panoramas, flash photography, events, etc,. For the first time in my photo career, the camera body brand is the least important part of my system. I have a LOT more invested in everything else. For me, the combination of Nikon D800 + Pentax K-3 currently gives me maximum flexibility and IQ in a very portable system.
YMMV
