Practice Ideas for piano

It is the summer now, and I need some suggestions on what to work on. I was thinking about doing one J.S. Bach invention every week. Then I would work on Haydn sonata in E minor. Finally, I would start working on Chopin's Waltz D b major. Op. 64 No.1

I am also toying around with possibly doing Chopin's Prelude in D b Major Op. 28 No. 15

Again, let me know what you all think, I would love to hear some suggestions !
