A bit late here, but may benefit someone. Consider old fashioned hide glue. It takes a bit of effort to learn, but may be perfect for this use. I'm a luthier and use hide glue for a lot of my instrument building. It is every bit as strong as Titebond 1, but can be un-gluded \with some heat and small drops of hot water.
BTW, Titebond 1 doesn't creep, but 2 and 3 will.
