Looking at the source, the answer I find is that it cannot be done.
The culprit is the `getchar' routine, which reads (in part)

	do
		c = getcd();
	while (!globp && c == CTRL('d'));

Probably a minimal change to fix it would be

	do
		c = getcd();
	while (!globp && intty && c == CTRL('d'));

(see /usr/src/ucb/ex/ex_get.c and /usr/src/ucb/ex/ex_io.c.)  `map' and
`map!' in ex mode would still fail, but :map and :map! in open or
visual would continue to work (those work by stuffing the command into
a buffer and making globp point at it).
