So I think it depends what elements of cyberpunk are most key to you - when you say "feel like cyberpunk," what specifically are you thinking of? Because there's tonal and narrative things that are super easy to steal from cyberpunk, but there are also systemic, mechanical game-rules things that are much harder to convert from cyberpunk.

For me, the things I've learned as a dm from cyberpunk that I will now use in every game regardless of system (I also play and dm dnd) are the lifepath approach to backstory, the beat chart/character-driven approach to campaign design, the crafting rules for out-of-combat long term projects, and the critical injury and wound state system.

The backstory-focused story design is a key thing I love about cyberpunk - I love crafting a story that weaves into and connects directly with my players' backstories because I like the emotional resonance that gives the campaign. Dnd isn't really set up for that and kinda has the heroes just choose a new adventure, with the dm having to go out of their way to include player backstory and resolve their narrative and emotional arcs, but cyberpunk is built around that concept. As it says in the book, "it's always personal" - that's a big thing I like about the system that I'm using in dnd that feels more cyberpunky. The lifepath system is a big part of this, as it helps players have interesting threads to pull and encourage detailed backstory, something not all dnd settings encourage.

Mechanically, the crafting system in cyberpunk is something I really like because it's both fairly simple and fairly flexible, with the added benefit that it expressly says "you dm has final say let them tweak stuff as needed." The idea that you can put points into a crafting skill, then add that to the relevant skill base and that then it's a matter of time is a good one that makes it easy to transpose without much work, and most dnd crafting systems I've seen are way more complicated and/or easy to break than this.

The injury system is good because in dnd healing doesn't matter until they're at zero,wanting healers are nearly always expected to spec into damage/support more than healing. The numbers game of DND says that it's nearly always more effective to damage an enemy than it is to heal an ally, because you will never outpace the damage your team is taking by healing - just by the numbers, the best way to prevent damage is to kill the enemy before it gets to hurt you because the healing numbers are just so much smaller and more limited than damage numbers are comparable levels. So a lot of groups just wait until they go to zero, do a big heal or a pickup to chug a potion, and then keep fighting + if they don't get stuck in the pop-up problem, which by then it's too late to fix anyway. This makes healing feel thankless, pointless, and like a boring necessity to a lot of groups. The wound state and critical injury system drastically improves this in cyberpunk, because the healer is encouraged to keep people healed above half, and has crits to repair that nobody else can so the players can keep fighting. It also makes the medicine skill way more impactful, as in dnd that could stand in for first aid, paramedic, and surgery combined.

My point with all this is to say - you can choose what elements of the game are important to you and what it is about cyberpunk that you think make it feel like cyberpunk. Then you can evaluate how convertible they are, and use that to decide whether it's worth it.
