Sure, why not. I'd do it.
I scoff at our idiotic death worship. People who are dead are dead, get over it. Their personality, who they were and all that matters was all current in their brain. After said processes stop and the brain decays, there's no more person and what's left is just, you know, shit. Meat and bones, to be precise, an empty husk that doesn't deserve to be the center of affection or the point of a huge industry specializing in, y'know, funerals and related supplies.
Whether you believe in some kind of postmortem existence or not (I don't), I'm pretty sure we can all agree that the physical body of the individual probably has nothing to do with some kind of a 'soul" or what not. Bodies decay. Resultant decay gets eaten by worms. There's nothing in those graves but wormfood, and there's no reason to venerate it.
Wow, this is another rant that will surely piss some people off. Oh well.
More on topic, I suppose, funerals are nice. Quiet, and stuff. It's like a park, but with less dogs and joggers. I approve!
