It maybe better to sell the 120gal tank and buy a new tank for the sump, that way you could design it the way you want, also you don't have to deal with the over flows or the holes on the bottom of the 120gal, unless you plan on having the 55gal sump, maybe make it a refug, under the 120 and have the 120 feed it. Personal I think I would get an acrylic sump, that way you don't need to worry about a possible leak from the glass tank.
