The Flames actually do have this type of analysis already. The Pucks software shows where all shots come from. Using years worth of data you can assign % chances of scoring from certain areas on the ice. So they can modify SV% based on quality of shot and make a better corsi by taking into account quality of shot.
Had the chance to talk a bit with Chris Snow about this. What should be obvious is born out by the data. The majority of good chances are from the middle of the ice, from the slot all the way out to the middle of the point. But by far the statistically highest quality chances are from rebounds.
Several teams have modified corsi type numbers but are much more useful in that they aren't measuring all shots as the same. You need that extra step to get the numbers to be something more meaningful. Counting a shot from centre ice as the same quality as a shot from the slot 6 feet out makes corsi mostly worthless IMO. Hard for fans to do as you either need to subjectively rank shots as being of a certain quality or you need access to something like PUCKS to have the historical data of scoring % from every area of the ice.
