To build this associative array, you might try

:$?^$?,$g/\[\d\+\]/let b:a[getline('.')]=getline(line(".")+1)

This assumes

- the content of each footnote is only one line (snagging multi-line
footnotes becomes an uglier task)

- all your footnotes are compactly at the end of the file with no
blank lines between the start of the footnotes and the end of the
file. If there are, you'd have to manually specify the range to
cover the range of footnotes instead of using the
automatically-determined range "$?^$?,$"

You can then use

:1,$?^$?s/\[\d\+]/\='^['.b:a[submatch(0)].']'/g

(again, if you have blank lines among your footnotes, manually
specify the end of the text-range instead of automatically
determining it with "$?^$?") to find all the footnote-references in
your text and replace them with the footnote text with added markup
notation.

You can then do simple clean-up to remove the now-redundant footnote
block:

:$?^$?,$d

and reformat/reflow everything as you see fit, maybe with

gggqG

Hope this helps,
