OK Norm,
I think it would look OK crossways with a Utility type cowl for a handle tank (or an ordinary PT cowl with the tank cut off). These have the slots in the cowl running North South when the motor is East West. It might also make the snorkel easier to fit using a standard Powertorque snorkel, without turning the carby upside down.
Anyway this is just a trial at the moment. Can always start again.
Thanks
Jeff
