I think the control mechanism for the gold octobot is connected to one of the devices inside of Doc Ock's head. So, no, I don't think he could.
Seriously, as much thought as people put into this, I think it's simple why Slott had Ock over-look this: he's a dying man, who had very little time to live. Sometimes, you have to cut corners. Ock probably thought that by the time Peter centered himself around the situation, he would either be dead or too weak to do anything. He figured he would take the chance to jump ship and deal with Peter if he had to.
