Need Help Creating Mod For Puking Command

I'm relatively new to modding, but a general overview (you may have no idea what these things are but there's plenty of tutorials.)

you'll need to make an override of the toilet to start. this will be your custom toilet object that replaces the in game toilet.
you'll need to extract the normal tuning of the toilet. (this will be another override)
you'll need to change the tuning of your toilet to tell the toilet to do something different. Say change the behavior of sims to puke instead when you click on clean.
you'll need to look for the puke interaction tuning, get it's ID and swap it with the clean interaction.

^this is by no means a detailed account, I'm sure there will be snags, but that's the basic idea. It's taken me around a month, and many hours to get comfortable finding and reading the xml files to be able to dream up ideas and make them happen.
