My practice rope is held up by a chain too, closed with a large pear-shaped carabiner which I also run my rope through. This leads to a mild version of the dreaded tri-axial loading, but I'm not worried.
Pulling the rope through is pretty easy. I leave a cheap rope line going through the small screw link up all the time when I do not have the climbing rope on. I have a rope trap from swaygo that works like magic when I attach the climbing rope to the cheap rope and pull it through the screw link. When I go to put the cheap line back after practicing, the lip on the end of the rope trap catches and releases the climbing rope. Thankfully that only happened once to necessitate a second rope and climb to reset. I fixed that by wrapping some black tape around the end of the rope trap, but that little bit of tape makes it a bear to pull through, and think the tape could slip off and again levae me standing at the bottom with both ropes on the ground. So that is why I thought a pulley with a little more space and roll might be a good solution.
Admittedly, those details might have been good on the initial post, but it hard to know which are most important when the crux of the question was if it is safe to have knot block with a pulley.
I have appreciated the discussion and hope it has not induced too many eye rolls. I am new to vertical, have a lot to learn, but am hoping to do so and increase my skills.
