Personally, no, I can't.
I mean sure, specific situations will arise now and then where one could rule this would be the case, usually involving set-ups where the target simply doesn't have room to dodge or is somehow otherwise partially restrained. But for general use, two things get in the way for me:
1. In most cases there's room to dodge an incoming blow or shot* completely and that has to be accounted for.
2. The way I want to see it, nobody is ever perfectly competent and even the highest-level of characters will still miss (or fumble) on occasion due to sheer bad luck, in balance with the notion that even somebody who hasn't a clue what they're doing will sometimes get in a lucky shot or strike. against something way above their pay grade (one of 5e's better design qualities is that it flattened the power curve such that these very things can happen, as opposed to 3e where they cannot).
* - point-blank shots e.g. taken from within 10 feet or so IMO need their own discrete sub-system involving potential insta-kill and much higher damage possibilities, but that's a separate issue.
