I posted this one in a thread quite a while ago based on a '68 Camaro grille (ignore the headlight reflections in the bumper :dodgy: )
It doesn't quite look right but I reckon the '69 Camaro grille concept in your drawings would look more natural on our cars.
OH Yeh, you guys have me thinking now. I have an extra hideaway set up from a 70 Torino. I'm gonna start measuring at first light tomorrow....

And as good as it looks, this demonstrates exactly why hide-away headlights do NOT belong on the '71-73s: It makes them look like a logical evolution of the first-gen Camaro:
Put a standard hood on the Mustang chop, and you'll be hard pressed to tell the two apart at first glance. Only the turn signal shape and the taller greenhouse on the Camaro are the giveaways.
The quad headlight setup in the top right prototype isn't bad though (and I bet Luxstang will love the hood scoop!):
Funny how the bottom left concept is undoubtedly the source by which Ford restyled the '73 turn signals due to the forced relocation. Note the bumper blackout.
