I did exactly this scenario a month or so ago on my checkride. The DPE declared my engine was on fire what was I going to do.. Well, I simulated the steps and he replied the fire was out, but I needed to put it down. Where was I going. I had plenty of altitude and found a green field, likely wheat. I got a bit closer and saw another field, longer and appeared flatter. I changed direction and was asked what I was doing. I said I do not like that field as well as this one. Its longer, looks flat and is a better choice. I am currently on base ready to turn final. Oh.. I see was the response. Lets get out of here... He did not think anything of it. Your CFII may be like mine was. Secretly think that it is ok, but give you a hard time as its not the "proper" way.
Good luck on your checkride. Its worth it in the end.
