Trying it for yourself is more useful than asking what other guys "think". What if it was a great tactic or technique, but you didn't attempt it because someone online told you it was a terrible idea? You would get more value if you field tested it first then gave a field report for feedback.
However, IMO, this can work but you are casting a very, very small net to obtain a small percentage of girls. You could increase your odds by doing less direct openers and calibrating with rapid escalation.
