As someone who has done a lot of electronics over the years, a hacked(electrically) product is only a good idea if it produces a better product. Hacking it comes with risks to any piece of equipment connected to it.
Spend the $40. Get a replacement board.
I also noticed with my P1S there was a sticker on the SD card/slot saying it was not hot-swappable. So watch out for that too.
