The OP's proposition was to descent to "platform" altitude upon receipt of the approach clearance--which exactly what TW 514 did, such as a platform existed. And when would suggest they left 3300 feet? Besides, TERPS does not authorize the MSA as an operational altitude and it was trained that way, in any case.
