K3II + DA*300/1.4HDTC to D700 + 150-600?

Ive been debating if this trade would be worth it. Ive changed brands before- Im not a brand loyalist so please don't go there.

Pros for the current K-3II/DA*300/1.4TC setup:
dynamic range at low ISO
sharpness at low ISO (debatable perhaps)
8.3FPS without a grip (D700 is 5fps without/7 with grip)

Pros for the D700 +150-600
AF system-tracking especially
ISO performance, especially in the 400-1600 range which is useful for birds/ wildlife
Tamron and Sigma 150-600 lenses have faster AF, and focus limiters
stabilization will be in lens- so you can see it in the viewfinder- helpful for tracking
image quality in the ISO400+ range

This would be an entire system change. Wildlife is my focus and I can make everything else work around this. I don't have the money for a D610, DF, D800 etc. I have ruled out the D600 due to the sensor oil issues. Canon's 5D, 5DII, and 6D offer me no gains in AF performance.

I would life to get back to full frame (shot film for years). I like the bigger view finder. I still think of focal lengths in terms of 35mm equivalence. The K-1 is a nice camera, but its too expensive for me and don't think it offers any real advantages without affordable long lenses (i.e. not the 150-450).

My main concern is the 12MP sensor in the D700 for cropping bird shots. I shot a 12MP Rebel XSI- but I wasn't into bird photography at the time so the MP were never an issue. Is the 12MP a deal breaker? or are the quality of the pixels going to make up for it? I routinely print 8*10, 11*14, and sometimes 16*20.

The D700 is not the way to go for cropping. Those 12mp are spread over a much larger area than your crop sensor Rebel XSI 12mp camera was. The difference compared to your K3 will be huge! Even the K1 or D800 sensor will have less pixel density than your K3. You'd need like a 50+mp full frame camera to equal the pixel density of your K3, so you may only be better off getting faster, longer glass for your K3 if it's better low light performance and reach you need.

Stillshot2 is right. You'll be awfully disappointed when you crop. By my quick calculations if a bird is about 1500 pixels wide (horizontally) on a K3 with 420mm it will only be about 650 or so pixels wide on a D700 with 600mm. It'll be like shooting with 200mm (or even less) with a K3. Assuming my late-night math is right.

Actually the d600 might be the ticket. Nikon has made good on fixing the dust problem even on out of warrantee cameras.
