It would be interesting to read about why the two diodes and resistor work and
why the SD-8 will not work without them (unless a battery is connected).

I wouldn't. I'd use smooth conduit. Either regular plastic electrical
conduit or, as Joe suggested, something like lightweight plumbing
tubing. I'd suggest 3/4" or 1" if it'll fit. The corrugated stuff is
good for wrapping around wires that are already in place but I find
trying to feed wires through it later to be a pain. The reason for the
larger pipe is not necessarily so you can cram more wires in but because
the extra space also makes it easier to pull or replace wires later.

protector and use it to pull wires. The loom protector is lightweight but will
protect them from abrasion.

Leaving a "tied-off" line in the conduit to help pull a new wire through
is a great idea. But remember that when you use that line to pull the
next wire through, you need to also pull through another "spare" line to
tie off, awaiting your inevitable "next" wire pull...
Of course, I learned this the hard way... (Long story involving a
lengthy conduit run from house to workshop, and a new welding circuit
for the shop... Sigh.)

I found that the black 25mm OD HDPE sprinkler system tubing by Gardena
(2718) is very lightweight.
Fixing it inside a finished wing would be a problem. Wouldn't want it
free to move.

If you have a solid conduit with no pull string, you can send one through by tying
it around a wad of cotton balls and using either compressed air to blow it
through or a shop vac to suck it through. This works best in conduit under a
couple of inches in diameter, and where the conduit isn't already stuffed full
of wires. It definitely won't work in a split loom.
Another alternative is to disconnect a wire that's already installed and use it
to pull through a replacement for itself along with the new wires (and a pull
string for the future).
