I do something similar with common lexers for CSV and TSV shared between
more specific parsers and tree parsers in different directories. Since I
use ant for building my antlr grammars, I just added a copy task into my
parser targets that copies the *TokenTypes.txt from the common lexer dir
into the parser dir before the parser antlr task. I realize this isn't
exactly importing a vocab from a different directory, but it is a
workaround that works fine for me.
