Homebrewing DnD5e to a cyberpunk world. Advice?

My current goal is to transform the spell mechanics into quick-hacks, turn CPR roles into 5e classes, and cybernetics just giving buffs to certain skills or modifiers.

I also plan some other, smaller tweaks, such as leveling not straight-up adding skill points.

Does anyone here have some advice, maybe some resources to point to? I searched for something like the thing I am doing, but came up empty handed.

Edit: Thanks for all of your replies, I read each one.

I looked into the easy ruleset, and thought more about the homebrew, and yeah, it is going to be way easier to just learn CPR. Thank you all.
