No. The ETOPS check has to be completed no earlier than 3 hours prior to the scheduled departure of the flight on the ETOPS leg. If delayed more than 4 hours for a MX reason you need a new ETOPS check. If you return to the gate for a MX reason and don't leave within 4 hours you need a new ETOPS check.
ETOPS checks a pretty comprehensive and would not be accomplished in less than an hour. Southwest quick turns to and from the islands will not be possible.
