I don't think you will do mirror doors are based upon thin metal around them and then the mirror glass
as it does flex a lot when your moving them in bifold state I wouldn't want to open them for fear of breaking them
to use a mirror door it maybe better to go up to wood and then fit the mirror to it
or create a strength point at joints of doors and then using smaller mirror doors
take a look at this you will see what I mean by thickness and size of the panels
