Worse than getting blood out of a stone, but if I have managed to make something of what you have then it should work with 32 magnets.
With 32 magnets you will have spaces about the diameter of the magnets and that will be ok.
I don't know why you use rectangular coils with round magnets but again it will work. It would seem that you have spaces between the coils from your dimensions but that doesn't matter. Still no idea of the hole size in the coils but again whatever it is it will work in some way.
You need the magnets to be alternate polarity, depending on what you have done you may have to reverse some of the existing ones.
I can't decide what the magnets are mounted on, it seems to be a single rotor with no return disc. If the magnets are on a steel disc, give it a try it should do something.
If they are on a non magnetic disc then scrap it and forget the whole thing it will never be worth the effort.
If you can make a single rotor with magnets on a steel disc with magnets of alternate polarity and manage to connect your coils correctly it will produce something. Whether you can get a standard voltage at a speed to suit a Savonious I know not or care not, I can only help with the alternator.
Good luck.
