Sure, you should do it, I think, if it will be worth doing the way you can do it. Don't forget that being respectful of your family comes first, though. How you act in this situation is far more important in the end that any pictures you might get from it.
Waiting for the inevitable event is harder than the event itself. You have my sympathy. I think we all have probably been where you and your family are, at least in some way.
