I believe the high downforce 905B version would still measure low in the front, only slightly better from the altered airflow, but would have significant gains in the rear because it is taller in the back. If this shape had good front downforce the 1.5 ton fullsize GTP cars would not have tended to fly. This was a big problem until that front undercar diffuser was well developed at about the Toyota GT1 time period.
Have you tried the Protoform Nissan P35 which is still available from Corally (at this shop:
http://www.pkracing.nl/, item number COR78226, 30 Euro, I think the picture is actually the narrow P-35, but you'll get a 235 mm wide one)?
The front end slopes up a bit more (it sits higher on the body posts), while the rear end is about as high as the 905B.
I can't tell you how it handles because I still need to try it myself.
