But it doesn't work that way...  getch will return a single number when
it sees

        a) a sequence of bytes
        b) within a short time interval, and
        c) the sequence is found in the terminal description's list of function

Generally alt+key isn't in the terminal description since it would make it
too large (except for special cases).  You could use ncurses extension
define_key to extend it at runtime.
