It can be extended south, it can not be extended north or west.
The Expo line literately turns east, so it can not go west without removing waterfront station.
Like realistically there is no option to cross at waterfront. It has to go over a new bridge at the Ironworkers bridge, which means a hastings line to go that far, and also a line coming from Metrotown before it crosses.
Crossing over the lions gate with a rail vehicle is never going to happen, the bridge would have to be taken out of service for vehicle traffic, and we know that is not going to happen. That is literately a Vancouver landmark, and even replacing it with anything that isn't a suspension bridge would draw ire, it would be like tearing down the golden gate bridge in San Francisco.
Maybe in an alternate version of Vancouver where we expanded the trolley network instead of switching to busses, the Lions Gate would have been designed to accommodate rail passenger vehicles. But as it is, it was not, and the climb to get there is likely too much for an adhesion rail system. Even considering the LIM's on the Expo line vehicles that might be pushing it.
The reason trains don't operate at steep inclines is largely because it requires more energy to go up the incline and thus requires more braking power to come back down. So you wear out your vehicles motors and brakes faster. If you lose your brakes coming down the hill, it's going off the first curve in the direction it goes. Likewise if you lose a motor going up the hill and it has to come back down.
So while I have confidence in the LIM to handle a 6.5% grade, I would think the comfort level of the passengers would make that a non-starter in the same way going around a tight curve at 80kph makes people uncomfortable from the centripetal force. Just because the tech says you can, doesn't mean the passengers do.
