Maybe not crazy, just not experienced in Keys Diving. The Gulf Stream current is farther out than nearly all the reefs at Pennekamp. There is a current in Pennekamp, but typically not bad at all. And if you were in the Gulf Stream, the current would be between 1.5 and 4 knots, typically around 3 knots. Never 5 knots, rarely 4 knots. The advice about checking out the patch reefs a little more than a mile out is right on. Problem is there is a lot of boat traffic. There is active kayak diving off Ft. Lauderdale, where there are 3 reef lines inside of a mile off shore. Again, lots of boats. Might be better for you. Getting back to Pennekamp, going out to the main reef complex is too friggin' far for a kayak. You have no quick way to get back in if a thunderstorm comes in, which is a daily thing in summer, and it can get rough really quick. I have seen it go from 1 foot seas to 3-5 foot seas in about 30 minutes. Not making that up. So could you do it? Yes. But it would be very risky and if you got back, you would be saying to yourself, "What was I thinking? I was a real dumbass for doing that." There is a gorgeous patch reef close in near Big Pine Key. It is not a far paddle off shore, just a far paddle to get there, because there is no place to park your car close by. Probably a mile and half paddle, but close to shore. Just east of Little Palm Island resort. Or you could pay $900/night to stay at the resort and just be 100 yards away from the reef.
