One idea I read years ago was to use thin mylar sheet. Roll it tightly
into a tube, slip it through the holes, then turn it loose. It'll uncoil
until it makes contact with the edges of the holes, then run your wires
through it.

I like it; can you get it in long enough sheets (at an affordable price)
to reach at least from tip to inspection plate and inspection plate to
root?
My plan so far has been to try the same technique using thin AL flashing
material from Home Depot a/c supply, but this sounds just as light
without the risk of cutting the wire on the AL.

McMaster-Carr has polyester (generic for Mylar) film in rolls up to 25 feet.
You might also consider Tyvek -- which is a non-woven (paper-like) sheet
made of polyester.
It's used as vapor barrier in housing, but I don't know if it would be stiff
enough.
FWIW, from DuPont's website, "TyvekŪ is DuPont's brand of spun-bonded
olefin - a high-tech fabric created" by DuPont from high-density
polyethylene (HDPE)
