I have seen various curriculum proposals, but the main problem is between the department of education and teaching unions. Teachers who can teach that curriculum are just not available. This threatens the teachers who clam up and whinge at the unions, who then moan at the department of education who back down and the cycle begins again. This is entirely self-destructive.
Remove the unions and hire ex industry people on a good salary with training and things will get better, but the current teaching standards across the board is just incompetent dross (bar about 5%). Teaching is not a profession at the moment. It is simply an easy career path for certain types of personality.
I include my wife in that statement as well and she would agree (she is an art teacher and there is very little space for her in society as a traditional creative person).
So summary: great idea, lacking any likelyhood of being executed unless they destroy the unions and hire better people.
