Depends on how many of these guys end up in the MLB pen. That may be the one good thing about Hicks: he'll keep a kid as a starter.
Assuming all are healthy, including Dobbins, Crawford and Sandoval, we have 8 pitchers looking at the 5 man rotation, not counting Tolle & Early!
Crochet, Gray & Bello are locks
Oviedo, Sandoval, Crawford, Dobbins & Harrison are the others. 1-3 might go to the pen, but assuming none do, our AAA rotation might be:
Crawford, Dobbins, Harrison, Tolle & Early-- WOW!
That leaves these guys for the AAA or MLB pen or traded or AA: Uberstine, Drohan, Sandlin, Mullins, E Rivera. That's not a bad AAA rotation, either.
AA: Bennett, Holobetz, Wehunt, Rogers, Dean (2-3 look promising)
A+: Valera, Fajardo, Witherspoon, Phillips, Eyanson/Aita (looks awesome to me)
