I guess the answer to that question is up to the individual. To me, you bet it'd be worth it! I thought the same on the recent thread about the other mare that died after foaling (also freak accident), I'd be so thankfully that it didn't happen before she foaled! That baby may be the only thing that gets me through the lose of my mare!
Of course I'd want to do everything possible to find a nurse mare (more for the health of my foal, then for myself, I love bottle feeding), but I'd sure bottle feed if I had to.
