The walls will hold you.

What about your ceiling light, you would need to be able to reach 17'
right.

If you can reach light from extension ladder, then that would be better
than
step ladder.

You can always turn around on the ladder, sorta sit down, and paint the
opposite wall.
AND fix the light.
