I want to put permanent PVC "pipes" in the VF so I can just hook up my
wet dry to them and suction out crud.

That makes me think of my aquarium undergravel filters. Your plan is
to feed from the bottom, which makes sense. This would require a
bottom grid held clear of the bottom, covered with small rocks, and
then the other media on top, with plants. Under the bottom grid would
be the feed pipe teed with a gate valve to a drain pipe. All the heavy
crud would fall to the bottom and could be removed by suction or the
drain. There would be an overflow at the top to return cleaned water
to the pond.
Does this sound workable?

Our filter is made of PVC pipe. Its covered with a cloth of some kind, and the
rocks are about a 1/2 a foot deep. There is a valve that we can use to drain
water from the pond, after stirring up the water. We also take our shop vac
and clean both levels of the waterfall, which are also filled with rock.
