As part of the Sunningdale Widening study, roundabouts are proposed for the Wonderland and Adelaide junctions with Richmond remaining as an intersection with a roundabout suggested as an alternative.
Roundabouts would also work well where there is a lot of turning traffic. Best Example I can think of where one would work is Wonderland and Oxford as there is room for one there if the gas stations are redesigned.

For heavy-turning intersections like Wonderland and Oxford, I think another good idea would be to have the traffic signals be green with a left arrow in stages for each of the four traffic movements, with left turns permitted from both the designated turning lane and the leftmost thru lane. Kingston actually replaced a roundabout with an intersection with this type of setup, and it works really well. I've heard that the old roundabout was "awful" at rush hour.
Here's a Google Street View image of said intersection.
