I'm unaware of any Pro Hackintoshes. Here is a good overview of the feature set between Threadripper, Threadripper Pro and EPYC.
The price point for the Pro 3975X is not too much more than the 3970X most of us are using, at $2790 (there is a typo in the 32-Core table where they say the 3970X costs $3990; the MSRP is $1999). However, the price point for the Pro 3995WX over the 3990X is significantly more: $5490 vs $3990.
This price difference doesn't reflect the need for a new mobo since the socket is different for the new Pro models (so there's no swapping of the CPUs for a quick test). And then there's the ECC memory (in the referenced review, read the Comments section, users have found that the number of used DIMM slots affect performance and explain why).
In terms of performance, both use Zen 2 and little advantage was found except in memory performance. My guess is that except for the 3995WX (which uses 4 chiplets), the other Pro versions will have little improvement over our current CPUs in a Hackintosh. The next generation of Threadripper using Zen 3 will probably be a different story; they're supposedly due to arrive later this year.
