I think the NW may be related to your last A time being so long - in my experience, my sons last A is usually equal to or slightly less than his previous A times.
He's on 2 naps and he's 8 months old E.g. Atm, his 1st A is 3hr30, 2nd A 3hr15 and 3rd A is 3hr (if the 2nd nap is a catnap of 45 mins or less then I do 2hr45).
I've found that the final A time is key to preventing/reducing NW and also to prevent him from waking frequently during the 1st 1-2 hours after BT.
Have you tried doing PUPD or shush pat so she can settle without BF for some of the wakings (if you know she's not hungry and she's waking for comfort).
I'm no expert, still trying to figure out our ideal schedule myself but I HTH
