It depends upon the a/c type and the elevator design ("T" tail or otherwise). The blanking of lift on the elevator surfaces will cause nose up/down tendency dependent on design. Eg. when you have max. rudder input to one side (eg. right yaw), you expose the elevator surface to the opposite (left), hence, causing the elevator to lose relative airflow effect and therefore stall sometimes termed "elevator blanking". This may cause either a stall in conventional terms (nose drop) or nose up stall (deep stall?). Sideslip though, is commonly used to induce (induced drag) drag so as to lose excess height on finals. I quite comfortably (not the pax) did that 2 days ago to correct my miscalculated high and hot approach.
