It's short and adjacent enough in meaning (one person) that I think English could adopt it wihtout much trouble. "On who hesitates is lost." "Let on who is without sin cast the first stone."
Aside from a few idiomatic expressions, on is generally used in everyday French as the third way suggested - as a casual replacement for nous (we).
As for bringing it into English, would you propose to use the English or French pronunciation? I like the French, but can't think of another example of the nasal o that it uses in English.

I like the French word which serves as a sort of vague (in person and gender) third-person pronoun: on

We have an equivalent of On in British English (I'm not sure if it's used in America) but it's considered posh.
E.g. One is not amused.
