Whoops, before you do this, you might have to let vim know that b:a
is an array:

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

Oh, this also assumes that all footnote-references have corresponding
entries in the footnote block. If you have a [13] and there's no
[13] footnote at the bottom, that substitute will yell at you about a
"E716: Key not present in Dictionary: {bogus footnote}"
