Placement Of Tank?

[Nano]

So my wife and I are a little concerned with the the placement of our tank in the room, its only 60g so I doubt weight is an issue, its just there is a well beaten path in the floor as its the highest area of traffic in the house. Basically what I mean is the floor has a bit of movement too it, so the tank moves a bit, not the stand, but the floor beneath it. so I will post a pic below of how it is in relation to the floor joists, and how we would like it as the floor is completely solid with no movement in the spot we want it.
If anyone could let me know ASAP as I want to move it today lol.

here is the pic, top is how it currently sits, bottom is how I want it.



Here you can see how it is and why I'm limited upstairs as to where I can put it. I can put it in the theater room in the basement, but I still have a lot of work to do down there first so I'd rather keep it up here where I can enjoy it.
Also yes there would be a window directly beside it but its north facing so little light comes in.
