Any way to mod V2 to make it so that when a Country is puppeted, it's territory becomes the same color as mine?

Think like the "sphere of influence" map mode, but on the regular map. I would be much more inclined to puppet a country if not only my name, but also my beautiful paint got spread over their clay as well.

The way I see it, I would probably end up playing the game in a more more realistic manner this way.
