Can that be done? Aren't those tunnels constructed with Iron Rings, similar to the Steinway tunnels which would make it next to impossible to enlarge? Or are you talking about replacing instead of rebuilding.I can think of no reason why it can't. Are you familiar with New Austrian Tunneling Method? This tunneling technology can be used to excavate the soil and or bedrock outside the existing iron ring liner to allow the enlarging of the existing tunnels.
