Hi Loic,
If the above rack is a planned rack but not yet an existing rack then my advice is to don't fill up the rack completely in one go. Start with some basic components first from what you have chosen (i.e. a few oscillators, LFOs, EGs, filters and VCAs). Get some experience with them and with that gained experience re-adjust your planning and thoughts and then add a few modules accordingly to that.
It's important to keep some reserved rack space free for future module extensions otherwise you are going to need soon another rack. I think rack-size-wise your rack size is okay but just don't start with a big number of modules in one go.
Good luck with the planning of your rack and kind regards, Garfield.
