Maybe you should just be okay with running 2 systems. Seems very common nowadays for photographers to run multiple systems. A friend of mine recently went all Micro 4/3, but he kept his 5Dc and 50mm 1.2 to use when he really wants that shallow DOF effect.
Maybe you can just keep that a7s with the superb 55mm for when you want to shoot in really low light.
Or maybe you can rent an X-Pro2 and see if the low-light capabilities are now adequate for your usage. If so, you could probably count on selling the Sony now or later when you get into the next-gen Fuji bodies.
I am currently just using both systems, but the a7S sees very little use compared to the X-E2 these days and I just feel like that money could be better used in other hobbies (I have an expensive list of those... ), but as I said, right now I still can't part with it since I do love it for those times I need it. If I could have it's sensor in the X-E2 body it would seriously be just about the perfect camera for my needs (but then I would need bigger lenses too ).

For my use in low light the very odd shot at 20000 ISO, mostly 12800 so the 5D3 was OK there & with a bit of work OK at 20 to - just don't look to close. The Fuji's are good at 6400 and the X-PRO2 is good at 12800 [very good] I now there will be a little difference in measurements though.
I'd keep the Canon but for the finance issue & I'm looking forward to letting go and having one system to work with and edit with. I'm lucky to be in a small pool of photographers who share gear as needed, so if I need it I can usually borrow something for a shoot. Problem I have is I really like owning my own gear so one more thing to try to let go off.
Yeah, I'm tempted to try out the X-Pro2, because if it really does give very good images (as good as the 5D3/6D) at ISO12,800 and somewhat useable images beyond that I'd be even more tempted to sell the Sony. I use the Sony for ISO50k and above sometimes though and for me the shots are still very useable (often comparable to the X-E2 @ a slightly pushed ISO6400), something my Fuji can't even come anywhere near.IMAGE LINK: https://flic.kr/p/GSiNPN DSCF2829.jpg
In good light though, the Fuji absolutely delivers the goods
