Running Cyberpunk with 5E D&D?

Ive seen a few posts around the net about using guns in 5e D&D. Mention of black-powder as well as modern. So it got me thinking, what would be that absolutely simplest plug and play way to run something like Cyberpunk. Just plug and play and run. So here is a quick shot at it.

Shotgun  1d12/1d6 piercing  30/200, 2handed

HMG 1d10 piercing spray, spray2, heavy, 2handed.

Double tap: take two attacks against the same target, do not add dex bonus to either shot just proficiency is it applies.

Spray: releasing a burst of rounds at a target. every possible target within 5' of the initial target must make a Dex save or take weapon damage. initial target of the attack takes an additional 1d10 on a failed save.

Spray2: Attacker picks a spot to attack, all targets within a 10' must make a Dex save or take x2 weapon damage, normal weapon damage on a successful save. Any roll 5 greater than the save DC take no damage.

DC of a firearm attack is 10+proficiency(if applies)+Dex adj of attacker.

Light Armor: as Studded leather.

Medium Armor: as Breastplate.

Heavy Armor: as Splint.
