No
Bonney can’t turn things into rubber. Bonney herself likely isn’t rubber.
She’s just an imitation of Nika, not Nika itself. Go look at her first Nika punch against Alpha. She never stretched or inflated her fist. She just transformed into a form with a giant arm.
Bonney has literally never shown rubber powers. If her fruit could actually do anything then it would be the strongest fruit in OP and would be treated as such.
But the story doesn’t value her fruit the same way it does Law’s or Luffy’s. It’s not a coveted power. Teach didn’t want it. Saturn called it worthless.
