It is most unlikely that WT & BOTH engines would fail at the same time. (Such craft would have no business being anywhere near a runway anyway!)
Who said both engines? Please don't insult our intelligence here. The aircraft would have to return to the gate if one engine failed to start.
usually there is an escape route away from the runway.
Is "usually" good enough for the airline industry? I don't see any escape routes at our international airport (a failure would require the aircraft to taxy along long sections of an active runway).

You would still need investment in all the pushback tugs (and their groundstaff) for windy or wet days.
Most airports involve some kind of pushback (will the pilots be steering blind away from the gate?). Don't expect Occupational Health and Safety to approve this..... They've already thrown our airport back to the dark ages in terms of efficiency.
