The 5D4 beats out the 1DX, there is no reason to get the 1DX. Canon doesn't offer what I want or need at this time. The 5D4 is great, one of the best cameras Canon has made to date, but it has shortcomings. The 1DX2 has other shortcomings. Put the two together, and I would be close.
I won't be out that much money. I always try to get my gear at the lowest prices I can. I have had the 5D4 for almost 2 years now, and paid then what people are paying new on sale now. Ditto with the 7D2. What I would be out would be akin to having rented the 5D4 for $250 each year. Not bad in my book.
The first round of changes would be the sale of the 7D2 and SL2, and a couple of lenses, the older ones that I don't use often. Not sure which I would look at, whether the a7r3 or the a73. Once I get closer to making a move this summer or late spring, I will know better.
May I ask what the shortcomings of both are of the 5D4 vs 1DXII for your particular shooting? What league are you shooting and from the sidelines or stands?
