The State of Utah did this back in 2000 -ish, by converting their technical (ATE) schools into campuses for the then newly-formed Utah College of Applied Technology. UCAT is fully accredited and on the state Board of Regents, but focused exclusively on 2-year Associates' degrees in vocational fields - CompSci (basically programming and systems/network administration), Nursing (up to RN licensing), Diesel Mechanics, Culinary Arts, a basic Business degree, CAD/CAM, and even a Cosmetology certificate (and subsequent state license).
You could then take that AAT degree, and convert it to a 4-year degree at any Utah state college (in fact, each UCAT campus was partnered with the nearest state college - The campus I taught at was allied with Weber State University in Ogden, and I was considered to be faculty and taught a few courses there, albeit while still on the UCAT payroll).
The cool part was that high school students could attend as early as their Junior year, and could, if they applied themselves, have a 2-year degree less than 6 months after graduating high school - all on the government dime, gratis. The classrooms were a mixture of AP-level high school kids and adults, and held day and evening courses.
