Yes and no. I used to do this back under 2nd ed. (Advanced D&D). All the later editions put a LOT more emphasis on measurement, making a play mat/map necessary. It's now close to impossible to keep track of flanking, cones of effect, blast radius, range, etc. for more than 5 or so creatures that way. You'd have to toss a lot of that out and streamline the game, but that might upset the play balance since a lot of tactics go bye-bye along with that.
