The small curb to protect the cylists is s great idea.

The main question I see is the location of the "Signal Stop Line" for the cyclist.
Is it before the opposing crosswalk (where it is required to protect pedestrians in the crosswalk) or is it just beyond the small curb where the cyclist "crosses" the opposing street?

If both Signal Stop Lines (for the drivers and the cyclists) are in the same place (which they should be to protect pedestrians), you are simply delaying the "point of potential interaction" between the driver and cyclist. In fact, the added distance could encourage a right-turning driver to "slip by" before the cyclist reaches the actual crossing point (i.e. cut off the cyclist).

However, by creating a 90 degree interaction between the driver and cyclist you increase visibility for the cyclist, especially in cases where the driver is stopped before making the right turn and a cyclist proceeds through the intersection at speed.
