That should be good. Personally, I would do at least 2 ounces of the FF for dry hop. YMMV
A local brewpub (Five Seasons) brewed an IPA with Falconers Flight, I think it's a very pleasant hop.
I don't have much experience with US-05, but I used it on a second runnings 'braggot'. (2 lbs of honey.) It finished about 1.010.
