I really like your thinking here Harris.
As Dwayne said, yes you ‘can’ do that. However, it’s not the most flexible or easiest way to do something like that. But I really like how you are trying to posit a different use for the information you are learning.
I haven’t ever found a need to go ‘full spaghetti’ mode with the driver mapping.
However, there is sometimes a need to fire a driver off at the 50% mark with different interpolation types though.
Hope this makes sense.

This might be for something like a corrective shape key which needs to turn on and then off at a specific value.
