Even a higher hydrated mix is averaged at 5% air. Causing a 3k mix to become a 2.25k - 2.55k product without vibration/consolidation. If an engineer specifies a given test, failure to consolidate will result in undermining the engineers specs if the specified test is ordered. With a 1.25 - 1.5 redundancy factor for most residential engineering specs these days, there would be a high possibility of compromise/failure during a seismic event.
