Valiant on craigs list

I am no stranger to cutting cars up and parting them etc.
A lot of people don't realize what really went on back in the day when these were just cars.............
However, i'm thinking that it might have been easier to convert this 4 door to a 2 door using his car for parts.
A 2 door post '69 Valiant is in effect a 4 door converted at the factory sharing the same roof, rear window etc. as a 4 door with different quarters, post, doors, and some interior stuff.
An experienced metal magician like you should be able to do this conversion fairly easily, most others probably not.
Wouldn't it have been easier (and faster) to graft the quarters, post, and doors off of his 2 door onto this car and have a better car in the long run?
From what i understand, his 2 door needed the whole front clip including inner fenders and frame rails, floor pan and trunk floor, and fire wall.
What are your thoughts on this?
