It hadn't occurred to me to check the original A6GCS's wheelbase, I just assumed it would be the same as the bodyshell at 94"
It's actually 90.9" which means it's only 15mm shorter than the wheelbase of the Triumph Herald/Vitesse, making them the ideal donor.
Both will also easily take a straight six. You'd need to take less than 70mm out of the front between the rear of the bonnet opening and the base of the screen, which you could do when converting to a flip-front for easy access.
