Hard to say what too much blue is, everyone has a different idea on that one, but in general I would not replace the actinics, especially if you're getting the "true" .03 actinic PC bulbs. They were just coming out when I stopped using Pc lighting, so I don;t know how they compare to the URI vho actinics.

One thing is you will probably lose a lot of PAR going from the 10k hamiltons to the 14ks. If this is an issue you might try to get 10k ushios; same bulb as hamiltons I think, and maybe go with all actinics on the PCs.
