I wonder if one could tweak the con loss suggestions above as follows:
Your Con score is the number of rounds that you can survive at 0 HP. When you get to zero, you start tracking the number of rounds. When you get healed, you keep note of that number. Perhaps, one could have a modifier as to the number of rounds one can spend at HP before starting to track rounds coming from the main stat for the character (not class).
That track gets reset every time you go up a level, or reach a major milestone in a campaign. In addition, you can go back one slot on the track by spending a day without any significant physical exertion, or by having a healing spell directed towards that, as opposed to your HP.
That would be a reasonable approach, reminds me of healing surges(though longer to regen). I would probably tack on heal checks in-combat "stabalizing" you so you no longer lose "con rounds" while at 0, but you're not up and in the action either.
