I think any changes they might make will be designed to tighten their control, not loosen it. I don't think they'll see any increased privileges for women or relaxing of any other rules. One of their biggest problems is their apathetic sales force that is spending less time knocking on doors and more time surfing the internet, or just trying to live a normal life.
I think any future new light™ will be something to increase their urgency - maybe a "new understanding" of some "prophetic scripture" that will strengthen their conviction that "armageddon is just around the corner".
