I like it, perhaps letting you have a second chance at all three casinos with the cap raised ~5000 caps. Having three perks, one for each casino on the Strip, that resets the tally would also work.
I wouldn't use them myself, ~30k caps is more than enough money in my opinion. Perhaps there should be three perks and each also has some minor bonus relating to the casino they represent. This could make them more worthwhile and add some character to . . . well your character.
