I really don't see that improving play experience. As dynamic as it sounds, it would really just come to the player's turn, he'd do full 360's looking around at static character and monster models standing around a essentially a chessboard. He'd then just have to ask the DM tons of questions about what his character can see versus what he can see. A static human standing infront of the halfling could completely block the hobgoblin from the player's view. In 'reality,' the human and the hobgoblin would be shifting around in their square, ducking, etc. The DM could just say 'go with what you can see' but that would, at least for me, create a ton of player frustration.
Trying to make a turn-based tactical combat system dynamic would involve spending a lot of resources making it appear a fight was going on constantly no matter how much time you spent on a turn, and what the player and character could see (what you see with your eyes versus what the rules say your character can see) would have to be the same. Even then, I doubt it.
