Keep in mind you could scratch the wood floors.
I wouldn't do it. For the same reason I am adamant about not lifting tanks with sand in them. First tanks are very weak, they become strong by design. When equal amounts of pressure are applied from the inside out, the panels push together to help support the weight. When you apply direct outside pressure you could easily compromise this and crack a tank. Same as leaving the sand in the bottom and then lifting straight up. When you have livestock, water, etc.. waiting around this is not the time to break a tank. Could you imagine having to source up a 75g at 10:00pm at night because you took a chance? Ultimately it is your decision so go with what you are comfortable with. A 75g reef drained halfway with the weight of rocks, sand, and stand could easily be 400lbs on the light side to over 600+ pounds depending upon how large a sump, skimmer, pumps, chillers etc... reside in the stand.
Another consideration to me is that I never reuse water. Tank water by nature is dirty. It really does not have the "seed" quality like live rock, old filters, and live sand. Think of it like this, tanks enjoy large water changes so why not use a tank move as a chance for a huge water change? Why would you disturb the rock and sand, causing a detritus storm in the tank and then add dirty water to that? Use all new clean mixed water to dilute the detritus that gets swept up during the move. Would you bathe in a tub of water that someone else bathed in before you? Of course not. However the tub will still have the ability to hold water, have soap, shampoo, and all the necessary bits for you to bathe with. So use new bath water.
