Yes, that would be the ticket.
Roll the silicone o-rings off the nipples and then pull the tubing away from the magnets. Cut the silicone tube a bit on the conservative side and test to make sure you want to make it shorter again or not.
An important point… make sure that you orient the magnets by clasping the two smaller magnets together and attaching it as a single unit side by side with the larger magnet at the bottom. This will align the N and S poles before re-attaching the silicone tubing.
