I would not consider tearing it down either. Not needed!
But if you do want to change it up some, there is a way that is far less drastic but still works. It doesn't disrupt things much to do small changes while letting things settle in between the changes. I have no ideas on what you may want to change so consider these to only be examples.
If you want the big plant to be farther to the right, dig a trench and try to slide the whole root clump over to the new location. It will disturb it and may show some die back for a time but plants don't die from moving. Far easier on them than being dug up, bagged and shipped? Small changes, moving things here and there works for me. When you consider what that means compared to what the normal plant takes during a move, it's a piece of cake to the plants. Feel free to enjoy your tank and plants as you feel fits!
