On-my-way upgrade

What do you think about little on-my-way upgrade? I would like to see ETA (Estimated Time of Arrival) upgrade. When pinged omw there would be a eta under the name of champion. This would help coordinate ganks, teamfights, and helping hand to chased player. I know it could olso make some confusion when someone ping onm on mid but instead goes top. But this can be avoided with thinking before using omw ping.
