before you try to "drag" the horn across elevated "forks", whether or not you "carpet" them.
This dragging and positioning issue is why I suggest a stable temporary "resting place" set at the correct elevation. This way you can safely and "easily" eff with, re-position and fight with the horn as you drag it back into the attic. The lifts will lift, but they do not offer a stable platform for this purpose.
If not a rolling scaffold with a wide, smooth, continuous surface on top (why not?) to drag accross, then a temporary platform built to serve the same purpose. You will save time and effort in the long run, with far less chance that anyone gets crushed or pops a hernia.
A "sliding plate" where you propose it would transfer a lot of weight to one raised lift, especially at first. Also, the horn is not actually smooth as you have drawn it, for "sliding" into the attic. You would still have to deal with all the "steps" built into the outside of the horn.
I forget if there is already plywood down in the attic, for a smooth run there, along with ample extra "floor area" there for a man to position himself to do this work, but this is how it should be prepared, to make it as safe and as "easy" as possible and to avoid putting a foot through the ceiling.
