Similarly to a question asked here, would mixing two solutions containing metallic ions in different proportions allow to electroplate something with the alloy of the metals? For example if I take a $\ce{CuSO4}$ solution and mix it with a $\ce{ZnSO4}$ solution, will I be able to electroplate brass? If I want to make 70/30 brass, would mixing a 0.7 mol/L and 0.3 mol/L solution work?
I know a "brass" solution can be made by reverse electroplating (is that the term?) a brass anode in an acid solution so mixing two solutions should have the same result, copper and zinc ions in a solution.
