Not dumb at all. I have also read an atricle on another site about using Aluminum Foil for BMF as well.
From what I can gather is you can use watered down elmers/ any type of white glue to make it stick.
Two problems with it though is.
One is can be a bear to work with and may look too thick for the scale.
Two is when you try to burnish it down with a stiff brush. It can leave brush marks in the foil.
