Although this is not exactly the same population, I think there is something to be gained from contemplating the vocational/technical school model (just as there is in the arts/magnet school model). These schools tend to be highly-enriched for out-of-the-box learners, too, including those with strong practical intelligence, entrepreneurial gifts, and an inclination toward experiential, problem-based learning. The vocational side of the educational model is oriented exactly toward apprenticeship, independent work, and real life experience (the level of research depends on the vocation/trade). On the con side, traditional academic offerings tend to be more limited, although many schools are moving toward virtual/online classes and dual enrollment for the highest-level students. And those academics may or may not be conventional in presentation. (In our state, an entire full-time year of college can be had for free, through dual enrollment.)
If admission to an elite university is a personal value or goal, then this might not be the most efficient avenue (although it definitely would give a student an unusual educational narrative, which might be an advantage, in some cases), mainly because of limited access to AP classes. But it should not pose a significant impediment to admission to very respectable second tier privates or state unis, including flagships, especially with dual enrollment or virtual high school credit.
