Help me to validate my piano startup idea!

Dear community!

If anyone ever searched for the notes sheets on the marketplaces, I have an idea how to improve the experience by dynamically changing the difficulty of some parts for the written sheet. Here's the link to a screenshot of the quick prototype https://ibb.co/F8G7RQt

I'm imagining my program will be able to configure at least 3 parts: melody line, bassline, and rhythm. This way you can simplify notes if you are a beginner or make them sound more sophisticated.

I would like to hear your thoughts! How useful this feature can be for you? And have you ever had troubles with finding sheets suitable for your playing level?
