How to attach the support frame to the mirror and film

[InternetPolice]

I am currently planning my mirror with two screens. Actually I am thinking about the reusability of the mirror in case the screen get broken and I need to replace them or other changes like adding light.
General Idea is to attached a black window film and glue the support frame to the film. So if I need to change the layout of the equippment, I can remove the film and adjust everything. My mirro shall be frame less, so hook or any otherkind of attaching is not possible.
In one of the Hardware forum somebody has tried it, but I can not find it again what the result was. May someone can help me out.
