That won't happen unless they move the fire station
I think that if the city was serious about improving Campustown, they WOULD move the fire station. But even if they didn't, why couldn't you make that block of Welch a one way access road? If the fire trucks need it to go north, they can, but no vehicles can turn south from LW and it wouldn't be a through street either way. That would allow the city to widen the sidewalks and allow some outside seating. But man, if they did move that fire station, what kind of prime property would that be? If they don't want to move it, why couldn't the city renovate the fire station and put the doors facing South? The fire engines would be rerouted and go around the block. Response time would be altered maybe 5 seconds if that.
