I think a 10 second penalty along with the card might be close to too much. And it is way harder to implement. Simplicity.

You want to talk simplicity and want a system that carries over yellow penalty cards from match to match? I bet if we asked IFI if the 10 second penalty would be possible to implement they would tell us, "that's simple."
