Hears a wight paper for you.. if I get the context correct

Influence of Ambient Temperature Conditions
Main engine operation of MAN B&W two-stroke engines

This explains my suggestions to reduce your day/summer and night/ winter IAT changes and shoot for a more narrow operating window. Easyer to tune efficiency fora smaller operating window according to the artical. To cold is just as bad as to hot.
The impact of intake air temperature on performance and exhaust emissions of a diesel methanol dual fuel engine
They ran there test at 1500RRM so comparable to the throttle loading an Ecomodder would use.
An idea
Air curtains leading the rear tandem driven by the ehxsost. Similar to this

Would your authorities have a problem with a removable wind screen with wipers, defrost , leaving the stock in place.
May or may not have to be DOT safety glass. As a solution to rigorous safty laws about redesigning the wind shield. Similarto what Aerohead is mocking up for the wind tunnel

Dreem big chisel down to reality
