I used to do this all the time for 2e and 3e. I was a big fan of relative positioning even 20 years ago.
Now, I run all my games online using Fantasy Grounds, so we use the tokens, but I still will often just use a whiteboard on FG and just do theater of the mind using the tokens for relative positioning.
I really like that better than full grid play, but I do mix it up and throw in a full-scale grid encounter once in a while.
