Hi Tobias, 
A colleague showed to me a polymer that is made to clean optical surfaces. It works like a glue: you pour it onto the surface, it polymerizes and then you peel it off like silicon with all the dirt and dust. So it should work temporarily like also as an adhesive to stick a mirror to another surface. The advantage is, its made for optics so it will not harm any coatings or delicate surface. See link below

Three thoughts:

PVA blobs which can be peeled after setting or hot glue (stronger -harder to peel). Nail varnish  is good too. I've used all 3 but YMMV depending on area of contact etc.

The problem is that I'd like to be able to remove the mirrors at some point without completely ruining their reflective surfaces and leaving too much residue on the glass and aluminum.
