Hey there hun & welcome to the forums:)
At this age, she really should be capable going 3 hrs between meals, and maybe even sometimes more actually, has she ever gone 3 hrs @ all between meals, and how long have you guys been trying EASY?
After how much A time does your lo usually give you tired signs? I think you can actually start extending A time a bit, so maybe try 01.25~01.30 hrs, as I think those 45 mins naps are UT, however if you get a short nap, I would still try to hold E time till 03.00 hrs, so you'd have something more like EASAEAS.
This is a link with sample routine, which could give you some ideas:
