It’s going to work things pretty hard to spin that large cone setting on the spool pin, and may even give you tension fits.
I had a Planters Peanut can that I cleaned out and set on the treadle frame in front of the pillar, put my thread cone in it, and took the thread up around behind the spool pin to go on through the thread path. It works great for a cone tower, but can get bumped off.
Later, I cut a boot top off of a Justin Roper cowboy boot, stuffed a plastic (butter?) dish down inside of it, and set the peanut can down inside of that to give things a little more “rustic” look. I put a black boot lace through the inside pull-on loop and tied it around the pillar so it stays put.
Caution: Without the nut can in the boot, the thread can snag on the boot pull-on loops. The can is smaller than the boot, so it holds the cone centered well enough for the thread to miss them. I used just a boot top on my home machine for a while, and I had to turn the boot inside out to avoid this.
