Bach/Chopin/Rach/Debussy preludes, Beethoven Sonatas

[poetsofthepiano]

Hi all,
I am an aspiring film musician from India. Here, music is all about melodic improvisation, lyrics, flutes, violins and a lot of other indian instruments. But I want to westernise the music here as well.

I intend to learn the preludes by Bach, Chopin, Rach, Debussy and Shostakovich. I also want to learn Beethoven's sonatas and Mendelssohn's Songs without words.

But here is the twist. I do not intend to learn them completely - I get all muddled up when I start exploring Counterpoint and fugal techniques and it takes a lot of time.
I intend to extract the melody out of each piece and the vision, technique and style of each composer.
So I will primarily be practising the right hand of all the pieces and adding accompaniments of my own and start improvising them into my own music.
In this way I save time, confusion and stick to melodic improvisation which is what matters here.

(Say a Chopin prelude would take me 2-4 weeks to complete it the way it should be but playing the right hand and adding my own accompaniments take me about 3-4 days. tested)

I have no pressure or need to perform any of these pieces but still want to be influenced by all of the composers mentioned above.

I intend to complete all of these in about 2 years. Is this a bad way to go about it? Is there a right way to go about it? Is there any other way I can go about it?
This is the next 2 years of my life, so any comment would be deeply appreciated and helpful.

Thanks
