Questions regarding extra pickup SR5

[piezo]

I just found out on this forum that SR5 's are now also available with HH and HS configurations. I did a bit of searching on the forum but cannot find any answers to the following:
- Where can I find those om the MM site? I can find schematics of the HS and HH, but no pictures.
- I assume the neck pickup replaces the phantom coil. Am I right?
- Are neck pickups and the 5-p switch (switchcraft?) available separately so I can put one in my SR5? And if so, does a neck single coil fit the phantom coil cavity? (I have not looked under the pickguard yet)
- Has anyone done that same modification? Important things I should know? (FYI: I do have experience in building and modding guitars/basses)

I think you would be better off selling your current bass and buying a new one with the dual pickups. There is more to the new basses than meets the eye; new preamp and such. I think your time and money would be better spent doing things this way.
