Lineup Adjustment Advice

Back story: I'm currently 7-4 in a league that has a limited number of pickups throughout the year. My record is decent, but if I lose last 2 weeks I could still potentially miss out on playoffs to guy I'm playing this week if he wins the following week as well and I lose. I currently have 1 pick up available because I've had a ton of injuires this year and looking for advice if any of you all would take chance on last pickup if you were in my shoes to try to secure victory this week.

Currently Projected Starters:
Ryan
Sproles (because Foster most likely out)
Sankey
Mega tron
Bryant
A. Johnson
Gates
Lions
Cantanzarro

Bench:
Foster
Bradshaw - IR
Foles - Out
Bowe
Daniels
Oliver
West

Looking at that unspectactular lineup I'm left with would you go get either:
A) Sanchez, Orton, Stanton, Eli, or Mett for potential more production this week at QB and probably safer move because I would still have 2 QBs on my roster
B) Another RB but all available is Sims (TB), Reggie Bush, Cunningham, and Joique Bell which all aren't great and would leave me with no pickups and 1 QB which is big risk
C) Let it play out and roll the dice and hope it all works out for me to still get a win final 2 weeks against 2 of higher scoring teams in the league

Any suggestions are much appreciated!
