I think you might find the Holydiver a bit too modern and compressed.
As far as magnets are concerned, I wouldn't worry about it too much. Ceramics are generally tighter but conversely, they tend not to have the same quality tone you get from an alnico magnet. Some alnico pickups, such as the A-Bomb, can also be just as tight as ceramics or in some cases, even tighter. They don't do a ceramic Black Dog anyway.
Based on what you've just said, I'm even more inclined to think that you'd really like the Black Dogs. They have a very PAF feel but it's a more modern interpretation of the classic PAF design, thanks to the 42.5AWG wire that tends to give it a bit more bite than a traditional PAF. It sits nicely between vintage and modern and honestly fits your description very well indeed.
If you really decided you wanted a ceramic magnet (I don't think you do) then I'd recommend a Cold Sweat set. It's a modern pickup but with a bit of a vintage feel and unlike many pickups from the contemporary section, it's quite open sounding.
