First, your question (contingent upon my interpretation of your question being correct):
I would try to package one of your OF (likely Upton or Victorino, maybe Quentin) with one of your backup SS or Uggla for a strong power hitting CI. As an above poster suggested, AGonz is a good choice, and you may be able to swing a Victorino/Uggla or Hardy deal for Votto. Those two will be studs this year. The leftover SS and/or Uggla will be a more thatn adequate 2B/SS, I don't see why you need 5 guys for 2 positions. Your analysis of your situation is correct in my books.
Second, you may get a little more response if you gave us the starting positions used by your league. I know when I read this, and by the looks of the other posts others did as well, I didn't know that there were 1B/3B and 2B/SS spots. Perhaps a few of the earlier posts were unaware of this and their advice came from this.
Anyways, good luck!!
