Patrick I have solutions for custom colormaps with alpha in Plots... Maybe this thread is good motivation to dedicate a page in the documentation. The gist is that you can pass in a ColorGradient, which you can construct with predefined gradient names, custom color vectors, and custom interpolation points. Do a search for ColorGradient in the Plots issues and you should find some examples.
