Only ABG I've ever heard that develops enough low end acoustically is the Ernie Ball Earthwood.
True, that has remained unmatched.
The thinner the top the more bass response, BUT ALSO the more feedback propensity when played electric. My one-off medium scale Gibson Super 4000 ABG is a case in point, lovely bass content, but you can't really play it above living room volume amped, the top already vibrates noticeably if a drummer in a rehearsal space just kicks his bass drum (unmiked)!
I also remember playing quite a few years ago an electric fretless prototype at a luthier (Mr Bassman) that had magnetic pups AND a Piezo in a small cavity in the body with a veneer-thin cover on top to catch the bass frequencies. It sounded incredibly acoustic and bassy over that, BUT it fed back above anything more than (again) living room volume. They never got the problem sorted out and it didn't go into production because of that.
I guess there was a reason why semi-acoustic basses died their death in popularity at the end of the 60ies when larger bass rigs became available.
