I suppose what you propose would be what the entirety of kindergarten should be about. Learning through various methodologies and then suggesting the best school for each individual based on what makes them spark.

No I'd propose doing it at different ages to see if interests change, and expose people to opportunity at different age levels. The key is giving people opportunity to hopefully be exposed to the thing they are interested in. Many things would not be something a kindergarten student would likely know yet that they have an interest in.

Failed miserably. But I went to a music college which got me into University studying music, and here I excelled and my passion for life was born

I only ever took ONE class my senior year that was music related K-12. I told you one of my passions was music. I played guitar, and I composed electronic music very early in that process. All which was self taught.

When I went to college the college I went to lied about having a Computer Science major when I got there so I was initially a dual Physics/Music major and the music was primarily so I could take the music theory and other classes I was interested in without being told they were not for me. Even in college I was eclectic and very much doing my own thing. I did play Cello (very little) in college.

I learned a lot of interesting things in college, but as with High School the bulk of what I learned was learned on my own outside of classes. I took heavy advantage of the library, computer labs, etc.

I played in the college jazz band for a bit so I'd be exposed to that.

Ultimately I worked on helping that college create the Computer Science major for there. Some of the students teaching Computer Labs were taught more by me than they were their classes. I spent a huge amount of time using the mainframe, and exploring the early internet pre-WWW.
