Okay, here is my addition to your idea. The point of my idea is that it will take zero transfers to get to downtown Vancouver from the core of each district, aswell as only one transfer between each of these districts... The districts I am reffering to Are Burnaby, Surrey, Richmond, and the southern Portion of Vancouver.
In this case, I continued the Ring line eastward beyond boundary, all the way to Kyle/Queens, however I kept the route the same. In keeping with the idea that NO trains should have to do the whole switching of direction at Waterfront, I continue the expo line to Boundary as well. Not it follows the original ring line suggestion south through Wellingdon and to Brentwood town centre. The difference being that instead of merging with mellenium line, it simply crosses it at Brentwood, and continues southbound too Metrotown, where it again crosses the tracks at the station. After this the intent is for the train to continue southwest until it hits Canada line, either in Richmond or South Vancouver.
The purpose behind continuing the ring line eastbound is to give the University there (SFU?) a connection to skytrain, and simplify that portion of the system (less stations running the two lines for millennium and Ring Lines). The purpose to the southbound expo line is purely to shorten the distances between the regional centres. with Construction of Canada Line, it will be possible to get to Richmond in one transfer, but by having the southbound line, it is possible to get to Richmond even faster from surrey or Burnaby with just one or two transfers (depending on whether the line crosses the river, or connects with Canada Line in South Vancouver).
I do this because I've read many times over that there is to much focus on sending people downtown, and not elsewhere in the region. I believe this to be true, and hope that it would allow people who live in Burnaby or Surrey to be able to take a more effective transit system to Richmond over a bus or car.
Here is my even shittier map, plagiarized from the guy above me. Sorry for not labeling any potential stations, I'm not THAT familiar with the areas on here. Only reason I have a connection to 52nd street is because I couldn't find a better spot to represent where I would want the track to end up (preferably in Richmond)
