Is your father a public figure?is he was an influential person?does this restoring the body of your father is for only family purposes or society in general?
This purpose is for getting money, or just for reminding only?if its for just remembering only I don't advice it,let's your dad rest well.
If its for getting money, also am speechless for that may be your dad said so before his resting. But its not good at all in our African cultures. Even my religion, Islam..doesnt allow this I don't know your religious.
