The rental car idea is a good one....but won't be possible from Leverick on Poker Run day -- the roads around Leverick are crazy that day and you won't be able to park there anywhere. If the Baths are a must, I'm not sure I'd plan that for Sunday unless you're planning to go directly there with the boat as you described above and use the kayaks....and Kris (Felix) is right - can't do a rental car from BEYC. But...as you've said...the best plan is NO plan. I think I'd stick with heading to Peter or Cooper and planning NS for Monday. L&S could probably get a car to you on Monday and you could stay on a ball at Leverick.
