It's an interesting idea to see if Model Review could handle this. I haven't tried that tool in a while, but suspect it might be able to handle it. The key would be to distinguish between the "Schedule Graphic" versus the "Schedule" itself. As you know, one schedule can appear on multiple sheets. Each instance on a sheet would be a "Schedule Graphic".
Here's what it looks like inside of Ideate Explorer, when filtering on the word 'panel'. In this project there are 25 panel schedules but only three have been placed on sheets so far.
If anyone gets this to work in Model Revit, please post info - I've always struggled to build out my rules.
