One possible solution to that is to make the material more of a discussion along the lines of: "what could s/he have been thinking? A or B? How would you feel in a similar position? What if s/he had chosen to do X instead of Y?" That approach would have stimulated the thinking and the imagination of the audience too.
The last ting they would want is JWs speaking freely from their own thoughts and imaginations. They have even cut out talks without outlines, they used to have talks with just one scripture and a theme. They would give these talks to Ministerial Servants or experienced brothers, now everything is outlined in the CLAM point by point. I was also informed that Public Talks were graded not based on speaking ability but how well one sticks to the WT outline. Basically, the perfect WT Public Talk has one original illustration and the rest is just the outline.
