Helix between staging levels

I made the return loop for the lower level staging at a 28" radius. The intention was to place my old helix, which was a 24" radius inside of this, just to allow continuous running between decks. As luck would have it, it didn't quite fit.
I accidentally moved the center line of the outer loop to far in, so I couldn't quite match the helix up with this. I should have made the outer loop at least 29". The way the helix was made it would have helped. I would have to also add another loop to get the height needed for the second level.
Now I have to decide if the helix is actually worth the effort to get it installed. I had the option for continuous running on the old layout and never really used it.
I have a couple of options to decide on
1. Forget the helix.
2. Rebuild the helix at a slightly smaller radius.
3. Forget the helix, but add an industry inside of the return loop on the lower level. The upper level is probably too high to do the same thing.
Time to put on the thinking cap again.
