F6 will not work with an E lens, my understanding is that one of the reason Nikon finally dropped the the F6, the other being all bodies are now made in Thailand.
I'm pretty sure dropping the F6 had nothing to do with the E lenses. Nikon has, literally, never made a film body that works with an E lens and made F6s for 16 years.
They dropped it because they were closing the production lines in Japan and realigning the Japan factory where they made them. No Nikons will be made entirely in Japan anymore. The factory in Japan will now only make parts and all assembly will be done elsewhere. The F6 just didn't have enough sales volume to justify setting up a new assembly line. The push into mirrorless and the rapid decline in sales of DSLR/Interchangable lens cameras forced their hand. They need space to make Z lenses, need to watch costs, they cannot afford to run a loss, and something had to go.
Back on topic, I chose the F6 over the F5, which was $500-600 cheaper at the time, based on maintenance. It was still being made so parts would be around and Nikon could repair it, but they announced the end of the F6 a week after I got mine.
That said, I'd probably be happy to get an F5 right now if I were looking for the same thing, a "modern" pro camera with lots of options. They're going to be harder to get parts for, but get a high serial number, well maintained example and gamble. Nikon made a LOT of them, and they are great cameras.
