This will be very complicated with minimal results
I follow the reasoning but I am skeptical about the efficacy of such changes. The imbalances in your hypothetical will certainly change the flow-rates into certain ports and/or into certain cylinders sharing a port. But to panic’s point the charge stealing is a function of valve events – so restricting flow into a ‘stealing’ cylinder will just richen the stolen charge; and easing the flow into a ‘robbed’ cylinder will lean out what is left with even more air flow.
As for selectively de-scavenging the exhaust (another interesting thought exercise) – the result will be exhaust gas left in the cylinder (reducing VE). If combined with restricted flow into a ‘robbing’ cylinder the mixture simply becomes even richer with CO and CO2 left over from the last Otto cycle.
Complicated with minimal results. But fun to ponder.
