70 Duster clone from a 73

Sorry if this has been asked, I did a search but couldn't find what I was looking for.

I am purchasing a clean 73 Duster but what I really wanted was a 70. My question is, is it feasible to convert the exterior to look like a 70? I am assuming I need to swap the hood, grille, front and rear bumpers and rear taillights and panel.

Thanks in advance.
