i think you would be alright, just make sure that you make your creation is very strong, you dont want to introduce raddles into your ht area, I would definatly use wood screws and not nails, also if you are going to have the 80’s at the ends of your stand I would make custom “stands” for the 80’s maybe a piece of wood that you would have to make a base for the 80’s to angle them down and possibly in a little bit, for better imaging, kind of like the movie theater does with the speakers angling them down towards the crowd.
