Modding Request: Painting Masterpiece Interaction.

Hi, as a painter in real life it frustrates me that you can paint a masterpiece work in a few hours in the sims 4, where as in real life it could potentially take years to create a unique piece of art. I would like to request a mod that adds a custom interaction to the painting easels when you hit level 10 painting skills. This interaction would guarantee a large, medium or small (depending on your choice) masterpiece work, however it would take 5-8 in game sims days to complete the art piece, while also costing 1000 simoleons to start. The painting format would only be the "paint from reference" format. As a masterpiece is guaranteed with this interaction, I would also like to see the chance to create a masterpiece from regular easel interactions significantly reduced for balance reasons. 

I know it is a very specific mod but I feel it could really balance out the painting skill as it ridiculous late game in terms of $$$$$$$ when hitting level 10 skill.
