I like the direction you're going here, but I would argue this structure is not unique to Kant. You could read Plato (or any idealist -- Schopenhauer or Philo or Hegel for that matter) the same way. The ontological structures are broadly the same, the difference lies in epistemology and the nature and origin of the formal epistemological structures to begin with.

Kant locates the origin of ideals/forms/categories in the mind only, as an essential pre-existing structure of the mind (think: hard-coded ROM), where Plato located their origins in reincarnate memory (not sure what the computer analogy would be there -- recycling a motherboard at Fry's?).
