Make Overworld and Nether structures spawn in the "same place"

It's quite possible no one will be able to help me, and even more possible that this particular feature just isn't super feasible, but thought I'd give it a shot. I have a structure that generates in the Overworld, and I am trying to have a structure generate in the Nether such that they are approximately nearby. At first I thought just putting them both in the same structure_set would work, but it doesn't--could be because it already made an attempt there. So, I just made a duplicate structure set with the same settings, but each spawning different structures. The Nether structure generates, however it doesn't connect as intended. In fact, they actually spawn at the same coordinates if you don't adjust for the dimension scaling, which means of course, the reason they don't connect is because of the dimension scaling. However, I'm not sure how I can adjust the settings for the nether structure's structure_set to get approximately the same locations when adjusted for dimension scaling. I tried just multiplying the spacing and separation by 8, but even with the same salt, it just makes them more rare, and doesn't guarantee connection.
