Why not three? One stream for creative types, one for practical types, then the rest. For the practical stream, unless it's changed, we already do this - from year 10 (about 15yo), Australian students can begin an apprenticeship/trade. From that age group, students are choosing electives and focusing on their strengths or interest, whether STEM or arts or physical electives.
And otherwise or for highly creative people, a grounding in most other things is useful. If you're an artist of some sort, you're going to be writing supporting documentation for exhibitions, or running business admin selling your work. To some degree, I think it's healthy for people to be pushed out of their comfort zone here and there.
