All of those players you listed either adapted from double-bass or electric guitar. Jaco chose to go forward on bass guitar shortly after his cheap'o double-bass fell apart and he couldn't afford to repair it.
To me, Victor Wooten is too late to be a benchmark. He has a style, but he is largely influenced by Larry Graham, and didn't set any benchmarks himself. He improved upon the techniques he heard before just like many other of his contemporaries. I'm surprised you didn't mention Larry's playing as a benchmark. He basically invented modern slap bass on bass guitar. Even Larry started as a guitar player.
I started to mention Larry Graham. He deserves the recognition for sure. By your definition, could Paganini be an innovator? He played an instrument that had existed in some form for more at least 1000 years by the time he came along.
