based on the list of free agents i'm looking at these are some of the righty bats that should be bench players available:
aaron boone
pedro feliz(might get a starting gig somewhere else)
bobby kielty
rondell white
reggie sanders
craig wilson
jose cruz jr
I think cheo jr might be a realistic possibility though for both parties.
If they trade Burke and give the job to Ransom, you get some pop off the bench but not enough. Abercrombie has pop in his bat, but he's not shown any consistency yet. I wonder if guys like Saccammano will be given a chance to win a spot based on the need. Usually you want a veteran to man that sort of job though, so you're correct on your list.
Kielty? That looks like a good fit for such a job.
Bench:
Blum = maybe left handed bat off the bench, backup at first, third, second.
Anderson, Abercrombie and Palmeiro = candidates for a fifth outfielder job.
Brad Ausmus = backup catcher.
Luke Scott = fourth outfielder, spot starter.
Burke = ubber utility.
If Coop carries 12 pitchers, that is the bench makeup if they sign Blum. If Coop carries 11 pitchers, then he one more opening. If Scott and Burke get traded, then Ransom is in the mix and maybe Keilty, with Abercrombie or Anderson moving up to fourth outfielder status (my bet is Abercrombie gets that job if Scott moves on).
Palmiero may be out of a job.
Good bench? Power, contact, speed, defense. All there, but will it mesh?
