I think you're attitude is refreshing and definitely not creepy. It's interesting that you've chosen several celebrities who, while attractive by many people's standards, might not live up to some expectations here depending on the severity of their condition. And it's all because of something that's out of their control, unless they choose to get an operation that is expensive (which probably wouldn't matter to them), but also tends to be painful and requires a lengthy period of recovery. It makes me think of how people might react toward attractive women without a celebrity status who are in the same boat. Could their feet be overlooked?
Though I think this thread is interesting as it is a change of pace, I'm not sure how many responses you'll get from girls willing to admit publicly that they have bunions. Even though you appear to be very tolerant, it seems as though this is a very touchy subject. But hey, you may get some PMs with people willing to open up which should satisfy your interest.
