It boils down to not outright making the wish about putting a leash on ACM monsters and HO-n-Run artists. Both skills would be adversely affected by having to worry about toasting their engines in the middle of combat. This might suggest the impression that air combat and it's outcomes would shift in favor of a different group. More mature, anlaretenative to technical minutia, and historical reenactment. Versus raw eye hand coordination and puerile chest thumping on ch200.
All engines during WW2 that I could find continuous run time testing info on, were not rebuilds like so many today in restorations. They were new engines with only break in time on them, well within the best part of their short 100-120 hour life expectancy. When we spawn, Hitech issues us a new low time engine with everything adjusted to spec with no fat fingering or over, or under torqueing by sleepy ground crew. One R2800 test of 150 octane failed because of fat fingering. The subsequent test, all torqueing of bolts was addressed by order, referenced to the Chief of the AAF, since 150 octane fuel use was top priority for the ETO in 44. That test ran fine, finding no issues with the continuous run time test.
Why not first try and get him to implement a random issuing of long time engines first, for random real life failures which can be partially mitigated with engine management in the MA. Kind of sounds like much of what came from the factories by the end of the war for our enemies as new equipment. See how that fly's with the general community for a tour. How many of them will pay $14.95 to be randomly punished? Oh I forget, the OP and company get off scott free by making Hitech the bad guy, with him imposing the punishment on the community for their hard earned money.
Now the AvA CM's could try and get Hitech to program something along those lines where you signed up for a given plane. Then ran it for 100 hours with all of the attendant aging problems and possible break downs eventually requiring an engine swap out. More like a game of hanger gas monkeys and their engines with an aside of getting shot at thrown in.
We get well veiled requests to make AH like WT or like IL2 or like DCS. Or some how merge parts of them into AH with no thought to how that would look to the competition. We never get requests to make AH like AH to stand on it's own from them.
