There may be a confusion here on what modding a game means - we cannot program this game, therefore we cannot actually add entirely new features that the game simply cannot perform. Your example is one of those things. What we can do with modding is limited to the things the game can already do, just in creative ways the game was never intended to do but regardless can do anyway due to quirks that are already present.
To give an analogy, modding and programming are like making food, say a cake. Modding ("coding", "scripting") is collecting all the material you need to make the cake. "Programming", on the other hand, is then writing the steps of the recipe leading to the cake you want to have and make the game, as it were, follow it. By this measure, we can only collect all kinds of different material, but regardless we have to follow the recipe to matter what, which means we have to try and match our material with the recipe presented to create a good cake, otherwise it will not work out.
If we wanted to implement such a thing as what you suggested (and btw, suggestions are not wanted, so please read the rules), it would require the source code of the game so we can change it on a more fundamental level, i.e. following the analogy, "be able to rewrite the recipe".
Okay, thanks for the information.
