Yes I've done this, and no I don't recommend it for the simple reason that you will find getting rid of the inevitable surface scum a complete p.i.t.butt. The various surface skimmers for your skimmer or a cannister filter odn't work as well as an overflow,and scooping it out on big tank is a different kettle of fish to doing it on a small tank.
I ran my tank up to the overflows for a while as I had had hassles moving house, and had the display in place, but not the sump and plumbing, and it took some months to get done. Also you need to keep all your equipment in your tank, or as hangons, which is never as good.
But as a temporary measure it worked fine, except for the surface scum.
