I like it... but I don't see the upside for the Rats.
Crawford, Upton, Zoberist (if they sign Hudson) would be a potent OF. Not sure how Hammer would fit in the mix unless the Rays are planning to dump Crawford sometime soon.
for the Rays - Willingham would be a cheaper alternative to Burrell as DH. Crawford and Pena have expiring contracts, so they might be interested in Willingham for beyond this year. They actually have another OF, Desmond Jennings, who is one of the best prospects in baseball, who has a good enough arm to play corner or CF (moving upton to RF). Pat the Bat is due $9m this year, so a Guz / Burrell swap, maybe some cash, helps them. We'd be stuck with Burrell for a year, but could stick him in either corner so long as he is healthy (and when he isn't, fine). Guz could be a backup infielder for TB, although they have Brignac for that role. Zobrist could play RF if they sign hudson, or, if Jennings is ready, they skip Hudson and go with Zo in the IF and Crawford/ Jennings / Upton in the OF this year. Cheaper and maybe better.
We then go out and sign Hudson / Kennedy. We'd be old short term, but something like either morgan in CF, 3 man rotation in the corners with Burrell, Dukes, possibly Damon, with Willie as the defensive backup and Owens / JMax / Beranardina waiting in AAA or as 6th OF.
