Regarding #2 - There was a recent WT "study" article that encouraged JWs to do good for others in practical ways. It was maybe 2 months ago or so (I don't remember the actual date). I can look through my (non-highlighted) WTs and see if I can find the quote.
If they were to maybe change the definition of service/ministry to include doing good for others, my guess is that it would be entirely to help keep their not for profit, tax free, status. You could meet at the KH on Sat mornings and break up into groups that would work on specific projects and report time spent. I know a bunch of pioneers that work at RBCs that get to count that time towards their annual hourly requirement so the concept isn't that radical.
I'd bet they'd actually get a lot more participation and those hours spent would actually benefit more than just the gas stations and coffee shops that current field service does.
Regarding #1 - I agree this would be a drastic departure from their current interpertation of Matt 13 but really, when did that ever stop them???
I see #1 as happening. #2 I think is the best idea they've come up with in years and therefore not one that will be implemented. If it is done, then at least the community would see some benefit.
