I think there are worse ideas. Depending on the tank setup, if you use lids ect., any 18" away should not be affected by salt creep. Dedicated electrical lines solve the electrical problems. The sound stage would not be worse than having a large TV in the middle. This will not improve things..
It also depends how careful you are with water changes and cleaning. Me, I need a huge concrete slab. The biggest concern I would think would be the noise floor. Any pumps and water movement in drains ect create noise.
