I understand the mention of stop removal, as it would be immensely beneficial, but it sits in the same realm of possibility as the elevating the at-grade segment of Line 5. City will never push for it, MX has no interest in mothballing infrastructure (even if it's worse than useless) and the whole neighbourhood would have a melt down if it was even attempted.
Project run times with TSP all you want, but the stops that are there, will stay, and it's a bit pointless to imagine what essentially amount to a rebuild of segments of the line.
