I intend to use four eye screws, pictured, to hang a wood-framed mirror. The mirror is about 44"x32".
But installing four eye screws (two on the bottom, one on each side, with a cable running through them, finished with a pair of L-shaped 2" screws in a wall stud) makes me unsure the 4 eye screws would be reliable for the 20lb weight.
And so I'd like to use some kind of "platform", sort-of like the one pictured below, that attaches with four screws and that has built-in some kind of loop, similar to the eye screws. I'm guessing that 16 screws would be enough for twice the weight of the mirror—a good safety margin.
A cable wire would then wrap around the four connection points and provide good support. I'd turn the cable into a loop with the contraption pictured below.
What kind of "platform" do I need, and what kind of screws would work?
The solid-wood frame is just shy of 3/4" (17mm) thick, and the frame is of an unknown grain, as pictured below. The only constraint being, to state the obvious, the screws cannot protrude from the face of the frame.

I am at a loss as to what "some kind of "platform", sort-of like the one pictured below " is supposed to do or how it would be used.
I would Use a french cleat and some stand offs on the bottom of equal thickness of the cleat so the mirror hangs parallel to the wall. ( Or adjust the thickness of the standoff to achieve any angle you like )
Another option is to use two D-rings on the back of the mirror with a cable and one or two solid (in structure or toggle anchors) hangers on the wall. This system is common for heavy mirrors and photographs .
Or another option would be to use Keyhole mounting brackets
The advantage of the D-rings and cable is that you can adjust the mirror to hang straight after it is mounted, but with the cleat and keyhole care must be taken to mount the mirror LEVEL. The D-ring is a more adjustable system, and the cleat and keyhole are more solid mounts, because the mirror cannot move around—even if bumped slightly—after it is installed.
