If not, then at least I may get a really good price doubling down.
Nope. You won't.
When SKF went to $250, and the carry rate went seriously negative, it was not a shortable stock. Your broker would literally auto-liquidate your short position even if you have cash to cover the losses, and not allow you to trade into the short side of that product. It happened in March 2009, and will happen again. This trade is a guaranteed blow-out. It is russian roulette.
Do the trade, just be sure to take your profits out of your brokerage account often.
