Apparently the fact that Bonvie isn't even Penguins property has completely escaped this ridiculous discussion. Just because somebody plays for WBS doesn't mean the Pens can call them up whenever the hell they feel like it. Bonvie's contract is with Wilkes-Barre, not with Pittsburgh. He would have to sign a contract with Pittsburgh, which would void his contract with WBS. Since it is after the trade deadline, Bonvie would be required to remain on the Penguins roster for the rest of the season, preventing him from returning to WBS to finish out his swan song. Aside from the fact that he completely sucks and would never be able to catch up to Cote to fight him, the business aspect of it should render this discussion mute.
My guess is that Stone will remain in the lineup for Sunday. He's tangoed with Downie before, he can do it again. In reality, Stone is about Cote's size as well. The Penguins have plenty of guys that fall into the middleweight category that can hold their own. Malone would count as a heavyweight and has shown decent fighting ability this season. Everyone on the roster, outside of the suspended Laraque, would get their ass beat by Cote. Hopefully it doesn't come to that, but there are plenty of guys on this team who will take an ass-beating if it means standing up for Sid or Geno.
