Probably both "/" operators would be directly visible,
so it would be ambiguous.  What's wrong with this:

    X.Struct_Length := BYTE(Integer'(Fac_Conf_Struct'Size / 8));

or perhaps:

    X.Struct_Length := BYTE(Integer'(X'Size / System.Storage_Unit));
    pragma Assert(X.Struct_Length*System.Storage_Unit = X'Size);
    -- Assert that it's an integer number of storage units.

or even:

    generic
        type T is limited private;
    function Size_In_Storage_Elements return BYTE;

    function Size_In_Storage_Elements return BYTE is
        Result: constant BYTE := BYTE(Integer'(T'Size / System.Storage_Unit));
    begin
        pragma Assert(Result*System.Storage_Unit = X'Size);
        return Result;
    end Size_In_Storage_Elements;
