To me, I think a not insignificant part of the question hinge on whether the notion of "Experienced" personalities version (or something similar) survives the transition.
The ability to show a figure going from average joe ; so average that he's literally not unique and you can have multiple of him running around ; to a special, noteworthy hero who get his power uniques was something I really loved. If experienced personalities remain, then I'd definitely want to still see non-unique with names, to create that link from the rank and file personality to the awesome unique. It was great thematic, visual shorthand for the way the story went.
On the other hand, if you're losing experienced personalities anyway (which I hope is not the case, but if it happens, it happens), then that aspect is lost, and while I'd still prefer a focus on named personalities (whether they're unique only or unique and non-unique both), it'd be less important.
