Now for your questions.

I'm not really sure what would've happened, I am not gonna go into speculation since we have little to no idea what the yomi yomi no mi can do, the only thing I know is that there would be no difference if he was flesh too, he'd be a zombie. Zombies don't age so he would still look the same. I can't think of anything else.
