Carter bbd
I know you don't want any out of the box suggestions...
Get a Weber side draft carb, make a 90deg adapter to fit the BBD manifold and the Weber flange. A bit pricy for the carb but I'm sure with your fabrication skills you can make an adapter that will set the carb lower than you need.
It could face forwards or backwards or to either side
Plus it would look rad!
