You already can make mystic sets. I have a blue mystic set in my bank, and I'm pretty sure you can do it with all the other colors too. As for the cannon, yeah, why not. Not like it'd harm anyone. just to say! you can't iv'e tried but one thing the mystic may get mixed up and think about dsylexic people mystic (gold) mystic(red) mystic(blue) very easy to mix up and cannon i think as well it will be good please help me :D
