So basically you are suggesting an entire box/sump on the outside of the
tank to
hang the skimmer on? This is a sumpless tank, and I'm not going to
drain the
tank to install a permanent overflow box in the corner either.

Noop.... Not an entire box / sump outside of your tank. According to your
pic.... It located inside your tank and from what I can tell, the water flow
over the top of the wall box and the pump push it out. Am I see the pic
correctly or my eye-ball need to be check-up? I assumed that box was meant
to be use as surface skim / clean. If I understand correctly from your pic,
why not create a grill so that the water will flow through / between the
grill to the box.

Ok.... Let me ask in another angle.
What this box do? My impression was... this box clean the surface of that
tank by flowing over the box wall and into the box, right? If so, why not
make a grill for the water pass through and go into your box. This way, it
will skim the surface and prevent critter that might get pull over the
surface and into the box.
