Can I put two large screws with spring toggles, or similar, into the

and just suspend the mirror off those?

I would use the screw-type plasterboard fixings.

I have used these to hang radiators on the walls, and the radiator
weighs more when filled with water than any of the mirrors we have (and
that includes a mirror we have which is real plate glass and a heavy oak
frame).

Hah yes but don't forget some of the weight rest on the pipes as well you
know. :-)
