As an add-on, you could deploy in a way like this:
SP: Valdez, Brown, Blanco, Arrighetti, Wesneski
Swing: LMJ, Garcia
Back-End: Hader, Abreu, (+1 still needs to be added IMO)
Middle-Relief: Scott, Ort, Whitley, King
If a starter goes less than 5, you use more middle relief.
If the start goes , you use a 2-3 inning swing guy to get you through the 7th or 8th.
Then you are left needing 1-2 back-end arms to finish.
The variability of the output should allow for the swing arms to be used on a relative schedule every 3 days. Therefore, 1 out of 3 days you have to use the full bullpen more deeply IF the starter doesn't go 6+.
