-Bishop Grandin and River Road
-McGillivray and Kenaston
-Lagimodiere and Regent
-Lagimodiere and Fermor
Some of those would require fairly large interchanges, but I think a simple diamond at Bishop and River would offer pretty awesome bang for the buck.

Personally I would completely cross River to cross traffic and eliminate the light. North on River to east on Bishop, head west to the Bishop+Pembina intersection, exit to Pembina, cross the bridge and access east bound Bishop. South River to west Bishop - use the existing U-turn on east bound Bishop about 1 KM east. Total cost - near zero. Impact to people that don't use River -- huge.
If they did that and built out grade separation at Bishop+Waverly you would have a nice long free flowing run.
Bishop+St Marys and Lag+Regent would both be hugely complicated designs. We aren't talking about just one intersection at either of those. St Marys, Dakota and Bishop need to be looked at as a single entity for grade separation. The land constraints and access needs suggest Bishop would be raised (or sunk). The approach angles either way would seem to infringe on the Dakota intersection. You could likely do a single access road running over Dakota for right turns on St Marys but also split traffic off to a diamond for Dakota.
Lag+Regent is a complete mess. The only option would seem to be to raise Lag. Sinking Lag is not an option due to the rail crossing. Handling left turns regardless of how it is down will be an issue due to the limited space. It would also need to take into account Reenders and the rail overpass.
In terms of easy fixes, I think one the city should be looking at now is Waverly+Wilkes. It is a bottle neck currently separate from the train tracks. We are spending millions to "fix" the issue at the train tracks to only have a bottle neck almost immediately south. A simple Wilkes fly-over and pushing Waverly under would effectively address that point and hopefully work towards solving some of the traffic issues in those areas by getting vehicles onto more streets quickly that stacking up on Wilkes waiting for traffic lights.
