I would try to get Jackson to make something like this.
-Ash body
-Natural finish
-Emg PJ set
-Black 3-ply pickguard
-Locking tuners
-3 pc maple neck with bullet truss rod,black block inlays and black fretboard binding
-Brass nut
-Jumbo frets
-Rickenbacker style bridge
I recently started using flatwounds because my main bass sounds unusually bright and I play with a boost pedal. Plus they feel much better for me compared to roundwounds.
