I think you could, but it is hard to tell what the glue will do. Certainly there is nothing brittle about them. The tongues have a crease from storage in a little box. Never laced until I got them. Still have the toe box tissue etc.
TBH I can't let my kid trash them and I can't wear them, so I will stare at them for a bit, document them (kinda done that) and then find a home for them where they can at least be worn lightly.
