Interesting that Option A shows the "future bremner line" on the map, while options B and C seem to pretty much nullify the possibility.
I think the moving walkways are a fantastic way to make a terrible passenger experience for the LRTs, shift existing and potential future transit riders to cars instead, and just generally make things worse for everybody.
There are a lot of problems with the Union Loop expansion, but I think it's the best idea. How many of the LRT passengers will be through passengers rather than being destined for Union? 10%-20%, maybe? I think it makes far more sense to have the direct Union connection, those few people can always just get off at Queen's Quay station as a shortcut for the through connection. Or if there end up being lots of through riders, they can run half of the trains straight through, and the other half to Union.
Option C is interesting. It lets the LRTs take advantage of not having to make the jaunt up to Union, but still gives passengers a potentially somewhat fast and comfortable connection to/from Union--though added transfers are still bad.
Edit: to expand on my issues with the moving walkway, keep in mind a lot of people in they city are very anti-transit. They're looking for reasons to avoid taking transit, and those reasons stack up quickly. Yes, it's a fairly short distance--heck, I make the walk through the PATH to/from the RBC building on Queen's Quay frequently instead of taking the 509/510 one stop--but people won't see it that way; they'll see it as an existing stretch of an underground, fully separated streetcar line being removed, and being told they have to walk instead, regardless of the distance and any walkways installed. Mark my words, if they proceed with this, people won't be happy, ridership will plummet, and there will be a lot more cars on the road in the area. I really hope they're smart enough not to do this...
