Absolutely. I say more that you have to be aware of it (in 5e at least), but I think we are talking about the same basic idea. I could go into more detail, but I don't think that is necessary.
Yeah, my guess is you're just not comfortable with dealing with the precision and calculation (though as Condiments says, its not difficult to do it in kind of quick eyeball-fashion, especially if, as would probably be a good idea, you aimed kind of low). Now, how the balance would look with PWL I have no clue, though like I said, I can't figure damage and hit points on both ends still weighing in pretty strongly).
