VIA Rail

Another possibility is a GO-height platform with ramps up to short higher sections at the door locations for Via. This requires careful control from the driver to stop at the right place but with proper design shouldn’t require the same precision as needed for platform-edge doors so should be possible.

I just realized a reason this might not work. If Via and GO coaches are different lengths, and if the specific different lengths happen to work out just wrong, then there might be no way to arrange the platform to put the high and low sections where they would need to be.
