It appears you are lengthening the wheelbase overall, correct?
Another idea would be to make a fiberglass copy of your front end (fenders and hood). Wouldn't be too difficult, likely save a good amount of weight, and you could encapsulate the front wheel wells. And you could bubble out to start a taper, continuing on the door, and then to your tail. Like:
Code:
/|\
|
|
___________
/ | | \
|W Motor W|
|W W|
\ | | /
\| Seats |/
\_______/
\ /
\ /
\ /
V
(Not quite that extreme, but you get the idea)
Would the negative aspect of the extra frontal area outweigh the benefits of a more complete teardrop shape? And that Code drawing took way more time than a simple Paint/upload/link would have..
