This is unlikely to work. Why? Whenever you impose a stringent system of categorization on top of information that eludes easy categorization, you will likely fail. “I’ll handle the edge cases” — that’s not an easy task. The edge cases add up, until all you are left with is edge handling. This reminds me of someone who lives in a theoretical, platonic plane without consideration for real world problems.

A system that has a higher success of working is developed organically, from the bottom up. I’d say Zettelkasten is one such example, though its primary beneficiaries are researchers in text-heavy fields (e.g. sociology).
