Far be it from me to disagree with Tim but this is about personal preferences. The Holydiver bridge and Emerald neck would have been my choices too, with maybe a Miracle Man as an alternative for the bridge, however, for the middle pickup I'd go a different route. I always found that I had the middle single coil set a bit lower so I always preferred a fairly hot single coil. I'd go with a Trilogy Suite bridge model because it's hot enough to match well with the others, it's modern enough to sit well with the others and it's hot enough not to get lost as well as retaining a distinctly single coil feel.
