I'm not sure if you mean have an R general inherit skills or have other generals inherit an R general's skills. Either way, my answer is the same: why would you want to? Every single R general in the game is terrible. Not a single one has a power, leadership, or intelligence rating above 70. Now that I look through the skills more carefully, there are a handful that aren't terrible. But that's not what you want to spend time and resources leveling up.
