I don't believe that things are going to get better at any other mass scale or by using any more modern results for the RG equations, so there's no reason to believe that there's any deep significance to any Koide-type relation.
We won't really know until someone finds a class of models which naively imply Alejandro's formula, and then performs an analysis like that in Sumino, http://arxiv.org/abs/0812.2103. As things stand, the situation is consistent with there being some sort of new symmetry which is visible only obscurely for the quarks, but which stands out sharply for the charged leptons.
