Its possible, there's been some bollocks situations Ive been into. Just recent was fuling camp, swarming with berserkers, shamans and deathsquitos, died an extra 4 or so times but never lost more than the initial skill loss cause:

had a portal moved closer and kept charging in. Die holding something so more gravestone markers spawn and then it makes it easier to get corpse run buff so then it's easier to get the original gravestone

So all you have to do is make sure you have a portal or bed on the island your exploring / sketchy area
