There's also the consideration of a downgrade if Sheppard is being really underutilized. It would cost in the order of 250-300 million to continue the Sheppard E LRT on the surface to Yonge. The subway could be retained as an express line or it could be scrapped...the latter more likely.
Any LRT connection via Sheppard/Yonge will have to deal with narrow section of Sheppard west of Yonge (up to West Don river), so a tunnel will be needed.
There is no dirt-cheap way to connect Finch W and Sheppard E LRT, but if we want to do it anyway, I think the Finch E / Seneca College option is the best. It will deliver more transit infrastructure at about same cost.
