Right,

Well, lets look on antrl3commontoken.h

API:
        19   pointers to func
                        32 bit os    19 * 4  = 76 bytes
                   
And about 
        11 * 4 bytes  of useful info


So there is chance that in c++ style
OR with single pointer on ala-VT  token will become

    from 118 bytes to 48 bytes
