Sounds dangerous to me. You're on final, which means that you're flying in a high-drag configuration (full flaps, possibly the gear down) and just a few knots above the stall speed when straight and level. All of a sudden you're going to increase power (torque effect, balance...) and you're going to make some turns. In a turn, the g-loading on the aircraft increases, and are you really remembering not to exceed 20 degrees bank here, and not to push the plane around with the rudder?
It sounds like a great opportunity for the classic stall/spin scenario, even more than the turn to final.
In such a case, first put the power on, get rid of the drag (retract gear, partially retract flaps), increase speed, then turn. And by then you'll find you're doing a go-around anyway. So turn crosswind and join downwind (might be late downwind) for a new attempt.
