I think the question is are you trying to add a more supple line to your main line so the jig sits more natural. This may be a good solution I'm not sure. But if you are trying to creat dropper loops and are happy to use the same leader material as your main line to your bottom most rig. Than a three turn overhand surgeons not is quickest and easiest. The top of the loop can be cut and you can directly tie a jig or hook to the line or the loop can be threaded through the eye of a jig or hook leaving the rig interchangeable.

You dont have to cut that loop, if line is thin enough just put it through like a dropper. I use this rig for tog fishing. Betweens rocks, snags and big tog, the knot has held up well.
But I would just spend the 2 dollars on a sabiki rig and cut it in half. 2 rigs for price of one.
Or you can tie a dropper. It's easy once you get the hang of it. Dont get frustrated is the knot pulls right out first few times. I've tried droppers for years and I still get some that aren't right.
