-all do respect Heidi, -as an automotive-designer i rather like Billy's notion of front-opening doors (maybe someone can do a convincing Computer-artist's photo of this idea just for grins)! If one has the financial wherewithall, why not something different like this, as it does not defile the lines of the car, -but will involve considerable invasive-surgery; and since the largest portion of the door is at the rear, -it actually makes sense! Getting-in is really not awkward and little different than with a '33Ford-roadster, -you open the door 60*, -then simply back your fanny in/down onto the seat and swing your legs in as you close the door! Question remains as to how one would deal with the exterior/door-handles (to say nothing of structurally "hanging" the doors solidly, -guess you could use the same rigid-hinges by just turning'em upside-down, and mount'em to a 3/16"-steel plate secured to the aft-jamb; -then swap door-latches left-to-right)! If i saw this done at a Custom-car Show, i know i would think "Wow, -how kool/clever that guy is"; and if well engineered, would surely add considerably to the car's value owing its novelty. One major problem though Billy, where are you gonna find space on your mantle for all of those trophies...

-Incidently, here really is a far more outlandish (black-paint would have helped, especially if only fnt.cockpit were open, and had chaffuer in tan w/brimmed-cap emulating a '30's-Towncar -Ha!) 4dr.-'78Vette 30"-stretch currently for sale on Ebay.com (use words- " 4-door corvette "); --of six-made, just two-survive, it was a totally impractical idea mfg.by Calif.CoachBuilders-Inc. (chassis must emmit more groans than a drive through a grave-yard at midnight); but note here, -the oem-angle of the C3's rear/door-jamb is not so great as to pose a major problem with Billys front-opening doors (lower/hinge-axis would need to be located far aft as possible to bring the common/hinge-axis as near vertical as possible) ...
