Let's face it. You cannot create true Cyberpunk mechanics.
First of all, i want you to read this analyzation fully, without skipping all way ahead. I am myself experienced with tabletop game of Cyberpunk 2020, and giant tons of video games, and i know, that system from Cyberpunk 2020 is too much difficult to be put in AAA game fully. Nowadays even developers of D&D games put only 4 classes in games and simplified mechanics, i hate that type of games, but CD Projekt RED wants to recreate mechanics, that even deeper and ridiculously more hardcore, than even D&D or shadowrun.
Mechanics of Cyberpunk 2020 feature over 90 skills and most of them could be combined into single skills. It has vehicles, driving skills for it, its tech skills divided into too much additional skills, and it has very deep charisma system, that if be put into game must be used every single dialogue with every single NPC, or it will not work as it was in tabletop game.
There only one decision, that CD Projekt RED can make, that will really save system with its full potential intact, its make Cyberpunk 2077 a topdown tactical turn-based rpg game, with vehicle system like from "The Fall Last Days of Gaya" (the only trpg i know, that feature vehicles in post apocalyptic world, i recommend to see it like an example of using vehicles in that type of games). Why? Yes, of course you want to enjoy another Mass Effect clone with bunch of real time shooting and cover system, but all skills and stuff from tabletop game will be deleted just for you to enjoy real time combat system. But this goes even deeper, in original Cyberpunk 2020 you can hurt yourself and cripple your leg, because of unlucky roll, and it happens very frequently. You cannot see a cover based shooter with fumbles, yes? You also should analyse the fact, you can have cars, bikes and even tanks in Cyberpunk 2020, Cyberpunk 2077 features hovering and flying for vehicles. This game could be a dream game of some school boy, that wants GTA with flying cars. But you don't want GTA out of your hardcore tabletop game, right? Because if it will feature real time driving, you can assume, that driving skill will be cut out, because if Cyberpunk 2020 character could fail to ride a vehicle right, if they are in a middle of firefight.
Next i should talk about social skills in this game, that feature oratory, interrogation, intimidate, resist torture/drugs (its a skill), streetwise, Human perception, interview, leadership, seduction, social, persuade & Fast talk, perform, authority, charismatic leader and streetdeal. Even shadowrun had much more simplified system than this game. So if you really want all this social skills be in Cyberpunk 2077 game, you should create game that has even bigger dialogues than Planescape Torment had! Developers must create dialogues out of skills, but not by strict script or (oh no!) cutscenes. But even voice acting will make much smaller opportunity to make deep dialogues. This game must feature most of this skills in every dialogue, to be like tabletop game, and it will not be, because every developer nowadays is lazy and we know it. Developer that don't want to recreate full potential of Cyberpunk 2020 in their game, could just take all this skills and make one out of them (Bethesda Studios like to do that stuff, you know how they can simplify the game), like charisma, but this is also will lead to deletion of giant bunch from that 90 skills of 2020 tabletop game. Lazy developer will delete stuff like biology, botany, mathematics, physics and even piloting skills out from the game to make it more linear without giant bunch of stuff to deal with. And this game also must feature VR, that makes it all more difficult. Virtual Reality in this game must be another giant open world location, to represent true tabletop experience, not some "level", that you complete and forget about.
Today's player too became lazy and don't have nice imagination to roleplay things, they just want another Adam Jenkins, Snake Eater or Witcher to deal with all trouble, because they want idols to worship, not character to play with and influence the game world by their own decisions.
Basically by today's standards we cannot create a game of a dream like Cyberpunk 2077 with 2020's full potential tabletop system, especially with all this technology advancement. Only if CD Projekt RED break them and create game that more realistic than any game ever created. But you will be sad in the end, its just not possible, even in distant future.
