I think we can all dream that we will all become one, but I highly doubt that will happen.
If the maximum aircraft endorsement number for flight attendants in Australia is still five then it would work perfectly with S/H & L/H crew endorsed on 737,767,330,747 working together as one and the A380 crew still remaining as dedicated crew.
How are the long haul crew enjoying the tandem economy service on the A330 SYD-MEL ? Would they be happy to do it on a 737 also ?
As S/H crew one international trip a month would be enough to keep me happy forever.
