I still think you need to rethink. Nobody I know / seen has ever needed that much hardware to connect front to back and hang shoulders and biceps from. The bridges are supposed to float in back and at higher levels are held in place buy the white elastic.
I've got...two parachute clips, sixteen inches of industrial Velcro, sixteen inches of white webbing, eight inches of black webbing, and half a stick of hot glue, holding chest to back, shoulder bells, biceps, and forearms. All on piece. Nothing moves.
Webbing doesn't flex if it's glued close enough to the middle. The parachute clips in the middle don't flex and the strap to the bells is glued between webbing from chest to back.
