Could you build this?

No This involves severe physical chemical engineering and life-critical hardware to safely perform high-rate water electrolysis underwater for human respiration.

What it would actually take: Developing this requires advanced electrochemistry for energy-dense, rapid water electrolysis, gas management systems to balance oxygen and inert carrier gases to avoid oxygen toxicity or hypoxia, high-capacity waterproof power packs, and extensive life-safety regulatory certification for human diving apparatus.
