"Supposing I'm making a turn from left base to final, and realizing I need to kill quite a bit of excess altitude" 4th Edition
Pushing the rudder into the turn is not an option due to stall/spin risk.
An aileron slip while turning is possible. To execute the maneuver, one would carefully increase roll to the left (left pattern) without increasing load on elevator, resulting in an increased rate of descent. The inside aileron goes up more, the outside down. Your approach speed is kept at a safe margin over stall.
What could go wrong?? If you practiced a simulated approach well above AGL, you would know!
The slip maneuver is safer for aircraft with low wing loading and ample tail volume as the tail will naturally lower the nose with increased VV and the wings will help reduce VV when you roll out. With practice, you do these all day long in a glider.
If you are flying a "brick", VV can get out of hand and high loaded wings will be much more prone to stalling if care is not taken to monitor VV, limit slip angle, and unload or even pitch down elevator while rolling out.
In all cases, the "round out" should start at a higher altitude due to the higher angle of descent (power on low angle landing can be "greased in" with hardly any round out at all).
Try it first at altitude. Practice makes perfect,
