I need crazy mod ideas.

Hello fellow Simmers! I have a suggestion for the game. There has already been some awesome expansion packs, mods and updates but I had an idea to make the game even more realistic. Just like in our real world, how about a mod that allows for an over dub of Simlish to whatever actual language the player would like to hear. The mod can create an option for the sim to learn a new language and give options for up to at least three languages based on the three choices the player downloads from the mod. Once the sim learns the language either from an online class, school or college they can then speak it to whomever they converse with. Tell me what you think of this idea. Maybe EA might put it in The Sims 5 if no one creates the mod. Thanks guys!!
