Could you build this?

Partial The question-generation UI and test flow are vibe-codeable, but an honest score with a margin of error needs IRT item parameters calibrated on a large body of real response data. Without that data, the scores would be unvalidated.

What it would actually take: The stack is a web or mobile front end with a backend that procedurally generates matrix, series, and rotation items. The hard part is calibrating item difficulty and discrimination parameters, which requires thousands of real test takers and psychometric expertise to validate the scoring and standard errors. Someone with psychometrics knowledge, plus a data pipeline to collect and fit responses, is needed to make the margin of error meaningful.
