Yes I actually have hot swap working after booting with a drive attached. It all hinges on an SSDT and being able to use ioreg to customize the SSDT. I will grab mine at work toomorrow and post it.
I am using a KGP X99 build. Although I have thunderbolt hot swap, it is only after I have booted with a thunderbolt drive attached. I would like to try this but my Asus X-99 AII bios is different, and my io reg is much different.

ASRock Fatal1ty X299?

Here is also I picture of my bios config for my slots. Sorry about the stretched image it's a super wide monitor.
Notice at the bottom of the list that in X4 mode USB3.1_EC1_EA2 and PCIEx1_2 are disabled. Thats because they would occupy the same address space. That means that XHC2 is not needed
