Is it permissible by code to install a new electrical panel over an old one?
If so may I pass through the feeder service wire via a chase nipple to connect to new panel?

Jumping in your conversation, sorry... I don't see how 314.29 answers the question. Are you saying the old panel is considered a box or handhole enclosure? And if you mount a new panel on top of it, it then becomes inaccessible?

Yes, It could become a j-box. But it must be accessible if their are wires left in it. It was the first code article thing I found. Their are so many variations.

No there in no wires left inside. From my understanding.

So... you are basically going to have a panel surface mounted on top of an EMPTY counter sunk panel?

And pull every cable out of the old panel and run it directly into the new panel through the top and bottom knock outs?
 
Yes

Yes. Including the feeder wires.
 
My take is that you can't install anything directly above or below a panel, if that thing is "foreign" to the electrical installation. That is not an issue here. The existing panel (whatever it becomes) will not be foreign to the new panel. So I would call it OK.

Something's not adding up here.
If there is no wiring whatsoever in the old abandoned Panel you're covering up,,, why do you need a chase nipple into it?

If so may I pass through the feeder service wire via a chase nipple to connect to new panel?

110.3 - Listed and Label and installed according instructions... I'd be surprised if there were installation instructions for mounting a panel on a panel, but maybe I just need to live a little longer.

I agree if the panel is gutted then your converting it to a pull box and the rules of 314 apply.

Not sure about that.

If the existing flush mount panel is gutted, and, the new feeder cable from the new panel comes down inside the wall from the attic, through that empty panel, and, through the nipple into the back of the new outside panel, how is that any different than othe NM cable you dont have access to inside the walls after they're closed up?

Are we talking about just a new feeder cable?
Or are all the existing cables and raceways still terminated per 312.5(C) ?
Why leave the gutted loadcenter enclosure there (actually a cabinet per article 100) if its just one cable ?
The reason the OP would want to leave the cabinet in place is the all the existing raceways and cables are not long enough to properly terminate on the new loadcenter per 312.5(C).
If the cabinet does not become a pull box under 314, I would ask per 300.2 what chapter 3 wiring method is a buried cabinet?
