I think that's not a wise thing to do against a stronger player. Stronger players actually start complicated fights to prevail through superior reading. It is possible however to win like this against a stronger player, if you make effective use of time management... e.g: leave lots of aji, then force fights with complicated variations when the opponent has limited time (e.g: towards the end game) to force mistakes or winning by time. These tricks are informally known as "timesujis".
