I think it's pretty unlikely. At this point, any value in rerouting through ORD (...Z9 ZN9 P7 PN0...) or IAD (...C9 D6 Z4 ZN4 P3 PN0...) or are they both pretty much equally unlikely?
Just monitor PZ spaces. Nonstop IAH-LHR is more difficult, but you have bought Premium Plus fare and travel date is Monday. Both should help your chance.
Good luck.
Edit: The later flight will have a better odd (P9, O5).
