AFAIK there's nothing impossible in them. It just happens that nearly no known
language uses them. As for marking them, why not using the IPA "retracted"
diacritic? (a minus under the letter) It is normally used only with vowels so
no ambiguity could arise. In X-SAMPA it is rendered as /_-/. So we could
have /p_-/ and /b_-/ as labiodental plosives.

That's THE big question. But since it's a conlang, why not simply decide that
the people who will speak it happen to distinguish them easily? :))
