hehe, I see some "arrows".....
The levels of the vector forces (those willy nilly arrow lengths in the pics) are not going to be any issue I am sure.
I can use "Visualised prediction of forces" based on experiences for that determination! LOL

Those tail 'bits of wood' can't really be screwed into the foam. But if you wanted to you could make some plywood inserts so that you had something substantial to screw into. I myself would also use captive nuts on that idea, and thus use 3mm bolts - 2 or 3.
I haven't looked/checked but most likely slits from below, to feed the plywood plate/s into - X amount inboard of the sides (eg 5mm to 10mm - the more the better!). Thus the bolt forces pull on the plates which have a large area against foam.
