I have emacs open with org-mode and evil and use it all the time. It's fantastic. I didn't need to make any configuration changes to org-mode to use it with evil.

Evil mode is still not set up enough like vim for me to use in my every day work, though. There are a few gotchas that are different. So I use vim as well as emacs. I just change windows in tmux when I want to use org mode. The only real downside is memory usage and it is inconvenient if you want to us capture in org mode (because you have to change windows).

I'm slowly setting up Evil to support my workflow. I don't think there is anything I can't do, it's just a matter of implementing it. Rather ironically, I used emacs for 20 years before I switched to vim. I have discovered that I prefer modal editing and having a grammar to describe my edits rather than directly editing things. You would think that I could switch back and forth, but it completely blows me up. I seem to have learned emacs keystrokes and vim keystrokes in different parts of my brain...
