Would it make things any faster, e.g. because it could use a more efficient internal representation?

For arrays of general Lua values, I don't see how you can do better than the table implementation, except maybe by pre-sizing the array part.  For arrays of uniform scalar types, this is exercise 29.3 in _Programming in Lua_.
