Depending on your use case, if you want something stiffer you could brush each sheet with slow curing epoxy resin, then layer and press it to create some DIY micarta (yes, micarta technically uses phenolic resin, but epoxy should work fine for most uses).
Unless you’re willing to put in some kind of response that basically says “I’m not going to respond to that” (and that’s a sure way to break immersion) this is effectively impossible to do well, because the writer has to anticipate every possible thing a player could say and craft a response to it. If you don’t, you’ll end up finding a “nearest fit” that is not at all what the player was trying to say, and the reaction is going to be nonsensical from the player’s perspective
LA Noire is a great example of this, although from the side of the player character: the dialogue was written with the “Doubt” option as “Press” (as in, put pressure on the other party). As a result, a suspect can say something, the player selects “Doubt”, and Phelps goes nuts making wild accusations instead of pointing out an inconsistency.
Except worse, because in this case, the player says something like “Why didn’t you say something to your boss about feeling sick?” and the game interpreted it as “Accuse them of trying to sabotage the business.”
