Dunno. It would be a shame to lose that sound of the ball thumping the ground to start of a match.
As for the wear and tear on umpires bodies, that's more to do with the fact the umpires are being kept in the game a lot lomger than they used to. They're older and their bodies just get older.
In earlier years the umpires would bounce the ball a lot more (every ruck stoppage, less ground umpires, 30 to 40 goals kicked per game) and they could cope. With senior umpires in the late 30s, it's only natural that their bodies start to break down.
