Well, what about

:let copyHash = map(copy(myHash), 'v:key == "information"?
(PREFIX_BARTEXT . " " . v:val . " " . SUFFIX_BARTEXT) : v:key == "clue"?
(v:val . " " . SUFFIX_FOOTEXT) : v:val'

? This assumes that PREFIX_BARTEXT, SUFFIX_BARTEXT and SUFFIX_FOOTEXT
are variables. If they are string literals, push them into the quotes
containing the space between them and v:val of course. I think that the
parentheses are not really necessary but that they make it easier to read.
