The two airboxes sit left and right of center and have little effect on blocking airflow.
The 1330 throttle body is forward facing. The still airbox is forward forward of that. The duct that couple the 1 airbox to the still airbox its over the steering unit. Airbox #1 is on the left side.
The airboxes could be removed, not sure you would gain much. The intake manifold would be more difficult, but someone with enough skills, time and money could design a new one. Lot of work though.
