The Overlea routing was partially reconsidered to allow the MSF to be along the line (as opposed to on a spur). If they’re doing that for the MSF, there’s no way the above will be considered.To follow up this is a quick n crude sketch of what I think a hypothetical Broadview South station could look like if aligned perpendicular to the GO tracks, thus allowing for future southward expasnion. I didn't measure the curves but they seem more than ample, the station would possibly be stacked (i.e - e/b and w/b on top of one another), and the proposed GO station...possibly nonexistent or moved east or west. Obviously this is fantasy stuff, but what isn't at this point. And it's a blank slate down there so now would be the time to propose something large and obtrusive like flyovers.
Naturally the bonus of this is if major sites were to come to the eastern waterfront in the distant future (e.g new NHL arena), or a change in land use with the closing of BB, the area could be served directly with a southward extension of the subway line.
