First modding. Need help

Hey Talkbass. I own a 80's samick short scale P bass (One Pickup) and wanted to do the following
replace the P bass pickup with a fender model one
Add a J Bass pickup at the neck and bridge
Add an 8 Way strat switch that functions.

Is this possible or am i in dreamland over here? i think the sound i would get is amazing!
 
the strat switch wiring will be the hard part. it might not be possible since strats have 3 pickups. honestly Id say you save your money for a bass that's already routed and then get crazy with wiring it. the squier jaguar would be a good p/j option.

He has a P pickup and wants to add 2 J pups. So it's 3 pups.

BTW Suburbia, make sure you check the pickup positions according to "projected" fret positions. This is a good tool to use: http://www.stewmac.com/FretCalculator For instance if your bass is a 19-20 fret, and you want a pickup in the Ric position, you should put it into the 24th fret position. Make sure you measure the actual scale of your bass more than once.
 
Thanks for the tips guys. Another option i was thinking is 3 les paul style switches but they function as an on/off and are next to the pickup they activate. Or maybe i could get arcade buttons and have them function the same way. Id prefer the les paul style though
 
I had a similar junker laying around and got mad scientist on it. Here's the mods:

Added a P pickup to the neck, used the original mid and bridge pickups.
I wired the bridge pickups to a 5-way rotary, giving 5 tones to that (bridge, both series, both parallel, mid, both out of phase).
I added a 3 way switch to allow the use of the P pickup alone, with the other pickups, or not at all.

It didn't take much room and it has a ton of tonal options.
 
It's a great first project on a cheap bass. Once you work out the kinks you can upgrade the whole thing.
Instead of a 5 way switch try using toggle switches for each one and have it so each pup can go in series or parallel to it self.
One thing I wanted to try on a pup with multiple p pickups was the in between sounds. Something like the bridge EA bass pup in series with the DG middle treble pup.
 
In the early 90's Fender had a 32 inch scale Stu Hamm bass that had all three pickups, with the P nestled between the two J's. If you can find a wiring diagram of it, then that sounds more like what you're going after. I wouldn't bother with the switch. I'd just go V-V-V-T with 500kohm pots so the load on the wiring doesn't dull out.
