Well, as a point of hope, consider this: while full power customization is still in the wings, what if they did something like consolidate all of the sprint powers into one power with a roster of selectable options, like the weapon customization? That way, a powerset would already have set animations and colors, you'd get a smaller selection than full customization, but you'd at least finally be able to have something that wasn't automatically the same as everyone else. Sprint: select slide, dash, rush, color-bubbles, etc. Not to diss folks that want to keep their different dashes all lined up in their fourth power tray...
Electricity: blue or red, ala Mu. Blasts in general probably have several permutations. Most healing effects are glows of various kinds. Granted this is more complex than simply a new model (as in weapon customization) but it offers a compromise that might be less of an overhaul to the entire character storage system.
