I think it will happen.
As mentioned above, the elder pool is getting slim. Most elders I know would love to just sit there and let some one else talk. They still get the elder power trip title without having to actually work as hard.
Like most things it will be "eased" in so as to be seen as good .
Maybe starting out with a tie in to the Org after the regional assembly to do a review of the assembly.
Next could be "organizational needs" similar to local needs but bigger. Most people will anticipate something juicy or "new light" but these will reapidly become fund raiser nagging sessions as that will be the biggest "need".
Maybe once a month "visiting guest speaker who is a GB helper" so that everyone can show up for that special talk.
Another innocous approach would be to occasionally have one of the service meeting parts - the ones where two brothers sit at a table and discuss something - be handled over the big screen.
Im sure there are lots more ways to do it so that it seems it has always been thus...
