You might spend a couple of thousand and still not be ultimately satisfied.
It sounds like you really like your bass so why not try out some different electronics. Repace the pots with some quality ones and maybe try some new pickups. You could even refinish it if you like but wear adds character IMO.
I've learned over the years that expensive doesn't always equate with better. A good playing bass is like an old friend but I also know what it's like to have GAS for something new... good luck
