If sororities thought that the fraternity-styled recruitment process would yield them more/better members and more stability over time, they'd adopt that style. Likewise for fraternities.

Our organizations have been around for a long, long time. They either know what works or they fold. If your organization can work within the rules its constrained by to reach a better result than everyone else, power to you. But your chapter's success doesn't indicate that everyone should work outside of the norm and expect the same result.
