If you've decided to replace the chain based on wear. it's strictly up to you. But if you're replacing the chain because it MAY solve your skipping problem, you may be throwing money away unnecessarily.
I mentioned 2 likely causes, one would involving replacing parts, but checking and adjusting trim is FREE and involves only a minute of your time. Since you don't know the exact cause, I think it makes sense to rule out the free one before spending any dough. But I'm kind of tight with repair dough.
I completely understand your point - but my understanding is that a stretched chain will wear out your crankset and cassette - so once one is stretched it should be replaced quickly so that you don't have to replace anything else. is that not right?
To be clear about your suggestion for the change - I would just need to turn the adjustment knob that is on my brifter a teeny bit to attempt your tweak?
