Search for the streamlining template on ecomodder.
That's the shape you want to approximate with the extension.
The better you match the template's angles (in both plan and side-views), the better it'll work.
But even when done crudely with flat plates, it'll work to some extent.
Obviously, in the real world it'd get too long to be practical, so you need to cut off the streamline extension.
The cut-off at the rear should be sharp and abrupt so the air separates as cleanly as possible.
Search for other folks' Kammback (or Kamm-back).
Reusing things is OK, but I think you're stretching it a bit
