I think selling your bass and buying a warwick corvette is a pretty good idea. Another option might be to swap your current pickups, which could save you a lot of cash. I took what was a decent Ibanez (old Korean made k5, mahogony version), and for like 250 installed, upgraded to a pair of EMG pickups that give me a whole array of very usefull tones, from thick and thumpy P Bass through the dual coil neck pickup, to burpy quacky fingerstyle Jaco sounds on the split coil bridge pickup, and then everything in between. Definitely a good investment. This might not be the sound you're looking for, but maybe a new set of Bartolinis are in your future, or Seymour Duncans? Both can be pretty aggressive in my eyes, er... to my ears. Especially if you like your current bass, how it's set up and how it plays, and just want to change the tone. Even swapping out the preamp could help. Make sure you have room for batteries before you make the jump though. Don't wanna be routing out a new cavity in your bass!
