First, it sounds as if the index was created manually rather than by
using PM's index markers. That's a shame. But if, perchance, index
markers were used, you can explain to your client that regenerating the
index is a simple matter.
Second, to answer the question you actually asked, you can do this (no
guarantees as to how the finished pages will look):
On each page, select the text block with the selection tool (arrow). Cut
it (Ctrl-X). Then power paste it (Ctrl-Alt-V). This puts it right back
where it was but as an orphaned story, not part of a text flow. Doing
this 100 times should take you less than five minutes.
Now, in making the edits on a given page, you may need to change the
page depth to fit the text; you may need to change the tracking of a
line or a paragraph or the whole page. You may need to make the block a
little wider or narrower. None of these are good design practices, but
you are between a rock and a hard place, so you'll make the tradeoffs
you need to make.
