Interlining to a larger extent was tried in Toronto in the 60s, and just resulted in a slew of problems, as any incident somewhere in the system backed everything up:
The TTC found that when the extra time waiting for a train from the correct route was considered, the time savings were not significant. Interlining was discontinued because of the confusion and delays
Here's a cool article about how transfers can be good:

It depends on the transfer though.
It didn't work in Toronto because the headway between trains was pretty long. So waiting for the right train took some time. Also, their system was flawed as at Bay street station there were 2 platforms, and trains to a single destination would alternate between the two floors. So if you were entering the station, you wouldn't know which platform your train was going to be on so people would wait in the stairs between floors.
In Vancouver where headways are short that is not as much of a problem. As well, we wouldn't have the multiple platform problem that Toronto had. At Lougheed, each destination would have it's dedicated platform.
I really don't think a shuttle would work, mainly because of Columbia. When trains are arriving ever 2 minutes in both directions, having a train enter the station and fully unload and fully load, then reverse direction would be a bottle neck. If shuttles are used, service levels on the Expo line need to be maintained, meaning more trains coming out of Surrey. The shuttle would slow them down a lot.
If the two lines are separated it would have to be at Lougheed where the 3 platforms would allow a train to rest while other trains flow through the station. The problem is that the switches there still require trains to cross each other's path, which to me isn't the greatest idea.
