I'm afraid I agree with a lot of people here. It doesn't matter if you find something that ticks every box you have, you'll doubtlessly tire of it eventually and sell it to get something else.
If it helps - I went through a similar phase where whatever I had I wanted something else, I solved this by downgrading from an expensive custom bass (Overwater Progress III) and bought 2 cheaper, but more diverse basses (G&L L2000 & Peavey T-40). There is nothing that at least one of these cannot do. If I get bored of one I play the other for a while, when I go back to the first it's like a new bass again.
I'm happier than I have been for years and have no desire for either of them to be replaced.
