I meant it is fairly common to have forms like "Vergili" or "consili" (genitives) instead of "Vergilii" or "consilii"; the contracted versions are more common actually in those cases than the uncontracted ones.

But I didn't say you are wrong to take the option you took with the uncontracted forms, I just found the statement
but -ii doesn't become a single long syllable in anything I've read (certainly none of the professors I've ever had have omitted one of the two i's).
somewhat bizzare, and only offered my opinion.
