The types of tones those particular artists use are pretty "vintage" sounding with great cleans. Can I suggest you stay more in the vintage arena with a pickup? You might want to stick with a 59 set or an Alnico II Pro set or a Pearly Gates set. The 59 and Jazz necks are the pinicle of great neck pickups for humbucker equiped guitars. The A II Pro will be the cleanest/brightest, while the 59's will have a bit more output while the Pearly Gates is just a touch hotter.
When you go with something like the SH-14, your starting to get into the higher output, distortion grade pickups. This extra output will cause the front end of the amp to break up a little more and your cleans wont be as great. I know that allot of those songs have allot of softer delay sweeps and spanky type riffs that will not come through as authentic because of the lack in top end you'll hear when comparing a Custom 5 to a 59 or one of the other pickups.
I really feel that the 59 would suit you well-its ironically the same EQ curve as the Custom 5, but a more vinatage typer output. My 2 cents
