Have you ever been at the bottom of a 40-foot pole with a weight on the
top, trying to guide it somewhere? It ain't easy.


I assume guiding the pole is the basic problem. The OP didn't say how
high the ceiling was, which might help.

I changed a 300W bulb about 40 ft up working from a tall step ladder
then using a standard light bulb changing pole and extensions. Three
light ropes were tied at the top to control where the bulb grabber went,
with 3 people on the ground guiding. After about 1 extension, you have
to guide the top as you add extensions. Working on a ladder allows
adding an extension under the stack. Extensions were around 8 or 10 ft.
You could probably kludge the extensions with 1/2 or 3/4" EMT and good
couplings.
