I've done a similar thing to my RBX270FL. Only difference is I went for a Wilkinson type bridge, SD vintage style PJ pups, rewired to VVT (was VBT), new jack socket and some new flat wound D'Addario strings. Overall cost was £260 as my bass was £90 (evilbay) and the Sd's were a bit more expensive.
Really please with the result, the VVT is particularly pleasant
