My partner is going bald and has started to wear a beard. Now he frequently looks just like his dad. This would be creepy enough, without the unfortunate fact I hate his father. Guh.
I don't think that reverance or respect for the dead needs the dead to be hidden from sight completely. It is the attitude that you bring, as a witness to a dead body, that matters, not the display and witnessing of a dead body, per se.
