Nice set up.

I actually kind of like the large insect look of the centered headlamps, though I find the E3 prototypes to have a more integrated look.

For me, the big concern would be the negative impact on cooling. I can't imagine that blocking the airflow to an air cooled motor would do the motor any good at all.

It would be interesting to take some temperature measurements of the heads, barrels, and oil tank after a long run and do a comparison to a car with 'normal' headlamp mounting. Do you have an infrared temperature gun?
