I doubt it can be done, simply because the electronic characters needed
to display shutter speed/f stop combinations like "1/250 f5.6" and so
on, simply do not exist in the makeup of the 88 board, and being the
OM-88 board is completely different than the OM-77,  you can't "cut and
paste" parts from one model into another.  Someone would have to
completely redesign the 88 electronics, and why anyone would invest so
much money  and time in such a camera model would be, well, laughable.

Like I said, it's like "modifying" a 4Ti to show liquid crystal f stops
in the finder.  Anyone who says they can do it is scamming you.
