I've done those sorts of exercises with the occasional student, as did one or two of my instructors with me.
Quite interesting how much control is available with judicious use of trim, power, flap & even weight shifting. So, yes, it is possible to land with this level of control - and without necessarily bending the a/c.
Of course other factors such as x/wind, length of runway, turbulence all have an effect.
It always fascinated me that the C150/152/172/182 would roll AWAY from whichever door was opened ie L roll if the R door is opened & vica versa. Can't remember if it was the same for C177 or C210.
The doors give quite remarkable roll control in those types. Otherwise the secondary effect of yaw (using rudder &/or differential throttles) is quite feasable.
NB: All the above is not EASY, but possible.
