Electroplating an iPhone

I thought it would be cool to electroplate the rear case of an iPhone 6 or newer since it's made out of aluminum. It's been a long time since I learned about the topic, so I looked online to research this, but hardly found anything about the topic other than some aftermarket companies that sell expensive gold electroplated iPhones. Is this a feasible DIY idea? If so, are there certain metals that would electroplate to iPhone aluminum easier than others?
