Hi;
I'm not sure how hard it was for you to remove the keyboard faceplate. I had no difficulty at all, because in my case, both faceplates were plastic sheet.
Based on what I saw, I think that it is not difficult to elect another sort of glue to settle them in place. I think "superglue" is NOT the best choice. I'd try some silicon-based glue, the one that would allow the thinnest foil betwen the faceplate and the case itself.
If there is another "laminar" glue available, I'd try, too. If I am not wrong, Ellis Easley (if it is wrongly spelled, forgive me) mentioned that there is this kind of "laminar glue" available. It comes in waxed paper so you apply it to one of the surfaces to be glued and remove the waxed paper. Then you have a "glue foil", ready to be applied to anywhere you wish.
If it did not confuse you, I think it will help finding the best glue.
Success. And please, let us know about what you achieve.
