Hmmm...
If you look at the property list of the tfm of an ex tex font (like cmex),
you will find something like

for integral text:
(CHARACTER O 122
(CHARWD R 0.472223)
(CHARDP R 1.111122)
(CHARIC R 0.194446)
(NEXTLARGER O 132)
)
for integral display:
(CHARACTER O 132
(CHARWD R 0.555557)
(CHARDP R 2.222246)
(CHARIC R 0.444446)
)

And now look at esstix afm file: this font claims to be AdobeStandard
encoded (!), and of course, most of the information that you need to make a
tfm font is not actually present. So it is not impossible to make a tex
system with esstix, but it should be a lot of work for the ex font.
Moreover, I am not quite sure one should be allowed to convert these fonts
in a mac format.
